Speed management You must drive at a safe and legal speed, managing your speed to suit traffic, weather and road conditions.
Maintain space to the front
You must adjust your speed to maintain crash avoidance space to the front of your car. The minimum safe distance needed in front is three seconds. This must be increased in poor conditions, or when you are being followed too closely by another vehicle. When you change lanes or if another vehicle moves into your three-second gap, you will be expected to create a new gap by gradually dropping back. To calculate a three-second crash avoidance space when following another vehicle use this basic technique: as the rear of the vehicle in front of you passes a stationary object at the side of the road such as a power pole, tree or sign, start a three-second count ‘one thousand and one, one thousand and two, one thousand and three.
Maintain space when stopped
Maintain space when stopped When you are stopped in traffic you must keep one to two car lengths from the vehicle in front to reduce the risk of colliding with it if you are hit from behind. You may move forward to within one metre once other vehicles are stopped behind you and the risk of being hit from behind is reduced.
Reduce speed
Reduce speed You must slow down if you do not have a clear view of the road ahead. Situations where your vision may be reduced include: blind corners; blocked intersections; crests and poor weather conditions. Slow down if you cannot see five seconds ahead. To calculate five-second vision in a curve, pick a fixed point in the oncoming lane that has just come into view and start a count ‘one thousand and one, one thousand and two... one thousand and five’. If you reach the point before five seconds you are driving too fast for the available vision.
