I have my theory driving test tommorow, can someone help me with stopping distances?

Question

What are the stopping distances for different speeds, how big a gap should you keep from the person in front of you, and how much more times is your stopping distance in ice than it is normally? Can you try and make your answers official, as in definately the right answer for the theory test. Thanks alot for your answers.

Answer 1

20MPH - 12 METRES

30MPH - 23 METRES

40MPH - 36 METRES

50MPH - 53 METRES

60MPH - 73 METRES

70MPH - 96 METRES

Stopping distance on ice is usually X 4 and stopping distance is in rain is usually X 2.

I had my theory last tuesday and i did well. Good Luck Hun :)  

Answer 2

Yes britbloke is correct - use the two second rule: say "only a fool breaks the two second rule" you'll feel a bit of an idiot saying it but it works - yes it is doubled in the wet (4 seconds) and times TEN in the ice - you will lose your voice from saying "only a fool breaks the two second rule" ten times but hey - in other words - KEEP BACK! lol!

Regarding the stopping distances - the way I remember it is using 50 mph (53 metres) - any speeds above that, the distance is more than the speed, any below that the distance is less than the speed. eg 30 mph (23m) or 60mph (73m) but that's how my mind works - I can't remember them any other way!

Answer 3

minimum 1 car length for every 10 m.p.h.night & adverse weather call for much more space between you and  the thing in front of you  

Answer 4

20mph - thinking distance 6m - braking distance 6m - total 12m

30mph - thinking distance 9m - braking distance 14m - total 23m

40mph - thinking distance 12m - braking distance 24m - total 36m

50mph - thinking distance 15m - braking distance 38m - total 53m

60mph - thinking distance 18m - braking distance 55m - total 73m

70mph - thinking distance 21m - braking distance 75m - total 96m

Distances are doubled in the wet and x10 (yes, times 10!) on ice.

Also, don't forget the 'two second rule' - I assume your instructor has already taught you this - if not, change instructors!

Good luck.
