Dry Steering

Dry Steering 
If your vehicle had the ability to feel and show emotions it would feel great pain and cringe when dry steering takes place. Dry steering mostly happens by turning the steering wheel, which turns the steer wheels while the vehicle is not moving. Situations where this can become a bad habit are, moving off from a stopped position, doing the turnabout and reverse manoeuvre.
Avoiding this is very simple; make sure you have the car moving before you turn the steering wheel. Even doing manoeuvres in tight spaces, use clutch control, bring the clutch up to just a little above biting point which will make the vehicle creep. Then steer quickly while you creep.  You will remember we would have touched on clutch control in October’s Blog on Getting the Bite. Also anyone who has power assisted steering will notice how much easier it is to steer when the car is slightly moving.

Tech;
There are many effects that dry steering would have on your vehicle if practised, none which are good. It puts a huge strain on the rack and pinion system, bearings, tie rods and pump. There is also a lot of unnecessary wear to the steer wheels.

Reading The Clues Others Give Us

I recommend that you practice the following, not only when you are driving but when you are a passenger also. This will allow it to become a habit, a thing you just do automatically.

Q. How do I know where someone is going on the road, as sometimes they would have an indicator on but not make the turn?

A. Always remember, an indicator on just means an idicator is working. There are three other ways of checking where a vehicle is going apart from the indicators.

1 Speed - Have a look at the speed of the car approaching the turn, has it slowed sufficiently to make the turn, which the driver has indicated on taking?

2. Position - Look at the position of the car. Is the vehicle angled towards the direction that the driver is signalling to go?

3. Wheels - Check the angle of the wheels. Make sure that they are angled towards the direction which is indicated by the driver.

Reverse Parallel Parking on the Left


Visit my page on fb  https://www.facebook.com/blackandamberdrivingschool

As with all my other Blog Spots, they are merely pointers on how to do things as I cannot possibly go into the detail that would be involved in an hours lesson. This is not included in the driving test in Ireland as yet but I think it is important to know how to do it.

Why is reverse parallel parking better than forward parallel parking?
Because on a vehicle with front wheel drive it is the front wheels that move, so there is more manoeuvrability reversing in. All that’s needed is to turn the steering to the left, the right and then straighten it. If you were to drive forward into the space a lot of driving back and forth would be necessary and chances are it would still not be correctly aligned with the kerb.

WHILE PRACTICING REVERSE PARALLEL PARKING;
I recommend practicing with just the car parked in front to begin with and as your skill improves and you begin to feel more confident, practice between two vehicles. Also make sure that the place you have chosen to practice is in a quiet area.

 Is the place you have chosen safe and legal?
 Make sure the space is at least one and a half to two lengths of your vehicle
 Signal left on approach to where you wish to park.
 Drive up along side the car that you intend to park behind.  Stop parallel to vehicle and leave 3 feet between your vehicle and the parked vehicle.
 Stop car at starting point and pull hand brake.

 Select reverse gear

 Look around again including blind spots on left and right side. Remember your observation must be done during the entire time you are doing the manoeuvre.

 Leave your left signal on while you do the manoeuvre

 As you reverse slowly and carefully turn the steering wheel to the left steadily as you reverse. This will need one full turn of the steering wheel.. (Don’t turn the steering to lock too quickly or your angle of turn will be out, which will mean there will be many unnecessary tries back and forth to get the angle of turn correct.)

 When your back wheel is about two and a half feet from the kerb start steering to the right again steer steadily as you reverse.

 When your front wheels are about two and a half feet from the kerb turn the steering wheel back to the left again which will straighten the wheels.

NOTE

How will I know if I have completed the parking correctly?
You will know that you have done the manoeuvre correctly when the front and back tyres are between half a foot and one foot from the kerb. When you start to practice between two vehicles make sure you are parked centrally between both vehicles.


What happens if another vehicle pulls up too close behind you?
You move on and look for another space. Most of the time, the reason a vehicle would pull up too close behind is that you did not signal in good time which would allow the driver following you to react and hold back.

Who has right of way when I stop to do the manoeuvre?
You must yield to other road users and wait until your way is clear and safe. This does not mean waiting until the road is clear of all other road users. Remember you are an obstruction on your side of the road until you park, so do so without any unnecessary delay as you would with the left corner reverse.

Can I position my left wing mirror down so that I can see where the back tyre in relation to the kerb?
Yes, however you must remember to re-position your mirror before driving off again.

Can I reverse Parallel Park on the right hand side of the road?
I would not recommend doing this. There are two many aspects in doing this that make it unsafe. Firstly you would have to go the opposite side of the road to take up your start position facing the oncoming traffic. Secondly at the time that you would want to get back out on the road your view is blocked as the driver seat is at the kerb side. Thirdly when you would manage to make proper observation coming out of the space you have to cross back to the opposite side of the road.

Getting the Bite


Visit my fb page  https://www.facebook.com/blackandamberdrivingschool

You will often hear people talking about getting the bite. What do they mean?
Well, let’s keep it simple; to get the bite or biting point you only need the clutch.
Check your gear lever is in neutral / out of gear and that the handbrake is applied / pulled up. Start your engine and put your car into first gear.

Remember, it’s the clutch that makes the car move, not the accelerator. The accelerator only makes your car move faster. So let’s not hear the car roaring, OK?

Allow the clutch to raise little by little with your foot, until you feel the car wanting to move or pull away. (There are three little tell tale ways of telling when it’s at the bite. You may see the bonnet raise a little, you may hear the car beginning to grumble and you must feel the car wanting to pull away.) It very much depends on pedal height in a vehicle, as to whether or not you can keep your heel on the floor while raising the clutch.

At biting point, make sure to put your heel is on the floor of the car. It is easier holding your foot at the same point if you are grounded with your heel. Try holding your foot in the same place in mid air for a few seconds, it’s very difficult.

When you feel the biting point, keep your foot in this position and let down the handbrake. Your car will start to move, with a see saw movement press a little on your accelerator gently and slowly as you allow your clutch to come up gently and slowly. Imagine you’re swapping the clutch for the accelerator.

Problems that may occur;
Why did my car roll back when I let down the handbrake? It happened because you didn’t trust your foot to hold the biting point. You dipped your foot back down on the clutch, bringing the car below the bite while letting down the handbrake.

Why did my car cut out when I let the handbrake down? You brought the car above the biting point too fast. Allow the car to move smoothly before letting go the clutch completely.  This really only takes a couple of seconds.

Remember, have fun with this, using the bite you can yes, make the car move but also make the car hold an on the spot position without the handbrake. When you are practising make sure it is in a safe and legal place.

I have often been asked by pupils at the learner stage, why it is necessary to move off using the bite every time. It is very necessary for safety reasons when moving off and for moving off on hills. Have you ever been behind a car and thought it was going to roll back into you? Remember, your car cannot roll back if it is pulling to go forward. It is a physical impossibility.

For anyone who wants to know the technical side of this, Here is a very brief explanation. There is a bar connecting to the front wheel axle which is stationary and a bar attached to the clutch that rotates and moves forward when you are bringing the clutch up to biting point. The rotating bar is moving forward to meet the bar attached to the wheels. When the two meet, it's love at first sight.  The rotating bar makes the stationary bar rotate with it. This is the biting point which from then makes the wheels move.

Think of it in simple terms the engine is telling the wheels to move.

Roundabouts .


Visit my fb page https://www.facebook.com/blackandamberdrivingschool

Q. How do I know which lane to get into, on a roundabout that has roads going off it at every angle, and there are no road markings?

A. Look at your signpost first, if the road you want to take off the roundabout is before 12 o'clock, or at 12 o'clock on the signpost you need to be in the left lane approaching the roundabout unless road markings or road signs state otherwise.

If the road you want to take off the roundabout is after 12 o'clock on the signpost you need to get into the right lane.

Where there are multiple lanes going in and off a roundabout there will be road markings to explain which lane to take.

Stopping Distances


Visit my fb page  https://www.facebook.com/blackandamberdrivingschool

Over the years the most common statement I’ve heard from pupils is:

“I’ve learned all the stopping distances on dry and wet roads just in case I’m asked in the driving test.” To me the correct reason for knowing this information has been lost all because to most of us, these are just another figure. I’m often asked, “How do I know for example what distance 169 metres is?

The reason for knowing this information should not be a means of being able to answer questions correctly in your driving test. These distances are given to keep everyone safe on the road where if the vehicle in front of you stopped suddenly that you would have enough distance between you and it to react and stop safely.

When during a lesson I’m talking to a pupil about stopping distances. I try to put it in terms that we all easily understand and give a visual way of seeing what that distance is.

We have all been stopped in a queue of traffic either as a passenger or the driver and so would know what 3 or 4 cars in a queue would look like. The average car is 4.5 meters in length.  The below guide should help get a handle on what the different stopping distances look like. Click on below charts for larger images.

Road Position


Visit my fb page  https://www.facebook.com/blackandamberdrivingschool

Road position on the straight - The correct road position is less than one meter from the left hand side of the road (kerb or hard shoulder)

Road Position turning left from a two way street - Keep within a meter from your left both on approach and during your turn. Remember not to swing wide. The same applies when turning left from a one way street. Always indicate to other road users in good time what you’re doing before you do it

Road Position tuning right from a two way street - Do your mirror, signal and blindspot routine. Move over towards the center line on the road staying close to it without crossing it. If there is no center line painted on the road, imagine where the line would be.  When you have assessed a safe time to commit to turning right, drive forward until the front of your vehicle is at the center of the road you are turning into. This is the point to start to turn as it will line you up perfectly to be within a meter of the kerb or road side. Always look into the road you are turning into before you drive forward into the junction. Remember not to over shoot the turn which is known as a swan neck.

Road Position turning right from a one way street - Do your mirror, signal and blindspot routine. Move over towards the right hand side of the road and from this point carry out the same procedure as you would when turning into another road from a two way street.

Road Position in traffic lanes - stay in the center of your lane.

Zebra Crossing


Visit my fb page  https://www.facebook.com/blackandamberdrivingschool

How to recognise a Zebra Crossing
Black and White striped road markings – flashing amber light on either side of the road. Also as zip zag lines before it. You will also see these zig zag lines on approach to other crossings as well.

How to approach a Zebra Crossing.
On approach to a zebra crossing the flashing amber lights are very noticeable. At this point you must check all mirrors and when you have accessed the following traffic adjust your speed safely for the crossing. Be on the look out for pedestrians that may be making their way towards the zebra crossing to cross. You may not need to stop. Predict what may happen when you reach the crossing. If somebody is about to cross stop your car at least a couple of meters before the first line you come to. This is a broken white line going across the road.

Why give so much room when stopping?
It can be very intimidating when a vehicle has stopped very closely to where you are about to cross.

Do I need to use the handbrake while waiting for someone to cross and if so why?
Yes always use the handbrake while waiting. The reason for this is if you were shunted by the following vehicle your feet would leave the pedals causing you to roll forward injuring somebody.

Can I wave to somebody to cross at the crossing?
No, never wave to pedestrians or other traffic. Why? Because if you were to wave, the oncoming traffic may read your signal to be for them, this would cause great mix up and create a dangerous situation. However you may try to make eye contact with the person about to cross. They are then in no doubt that you have seen them and are stopping to let them cross.

Can I drive on once the pedestrian has crossed passed my vehicle?
No, you must wait until the person has completed the crossing and has both feet on the footpath. Why? The person without thinking may change their mind and go back to the side where they started.

What should I do before proceeding to drive on?
Check mirrors – as to the whereabouts of following traffic. Side mirrors for cyclists and pedestrians. Check that everybody has completed their crossing. Release handbrake and proceed if safe to do so with caution.
