Speed isn't just about sticking to the limit; it's about driving safely and appropriately for the conditions. Learn how to master your speed for every situation.
While legal speed limits provide a maximum safe speed for ideal conditions, a truly safe driver understands that the "appropriate" speed can often be much lower. This skill is about developing your judgment to always drive at a speed that allows you to stop safely and react to any developing hazards.
Always be able to stop in the distance you can see to be clear.
Adhere to all posted speed limits and national regulations.
Maintain comfortable and efficient acceleration and deceleration.
30 mph (or 20 mph in Wales) unless otherwise signposted.
60 mph (unless otherwise signposted).
70 mph (unless otherwise signposted).
70 mph (unless otherwise signposted).
Note: Always be aware of signs indicating temporary or lower speed limits, especially for certain vehicles like those towing trailers.
The speed limit is a maximum, not a target. Your safe speed is determined by various dynamic factors.
Stopping distance = Thinking Distance + Braking Distance. These figures are approximate and apply to good conditions.
12 meters (3 car lengths)
23 meters (6 car lengths)
36 meters (9 car lengths)
53 meters (13 car lengths)
73 meters (18 car lengths)
96 meters (24 car lengths)
Rule of Thumb: In good conditions, maintain at least a two-second gap from the vehicle in front. Double this in wet conditions, and multiply by ten in icy conditions.
Always drive at a speed that allows you to stop safely within the distance you can see to be clear.
Adjust your speed significantly for adverse weather, poor visibility, and challenging road conditions.
While caution is good, driving excessively slowly can also be dangerous if it impedes traffic flow.
Safe speed is dynamic; continually assess and adjust your pace based on the unfolding situation.
