Safety margins Flashcards
What distance should you give to the car in front?
Enough room between your vehicle and the one in front so you can pull up safely if it slows down or stops suddenly. Your overall stopping distance is the distance your car travels
- from the moment you realise you must brake
- to the moment the vehicle stops.
This is made up of thinking distance and braking distance
In other conditions you’ll need to increase these distances to what?
When it’s raining or the road is wet - double the distance
When its icy - 10 times the distance
Signals warn and inform other road user, including pedestrians of your intended actions. You should always:
- give clear signals in plenty of time, having checked it is not misleading to signal at that time
- use them to advise other road users before changing course or direction, stopping or moving off
- cancel them after use
- make sure your signals will not confuse others. If, for instance, you want to stop after a side road, do not signal until you are passing the road. If you signal earlier it may give the impression that you intend to turn into the road. Your brake lights will warn traffic behind you that you are slowing down
- use an arm signal to emphasise or reinforce your signal if necessary. Remember that signalling does not give you priority.
You must obey signals given by who?
Police officers, traffic officers, traffic wardens and signs used by school crossing patrols.
