Allow time to react

Many speed related motorcycle crashes happen in good conditions with no other vehicles involved. Even experienced riders need time to react to changing situations on the road. Sometimes, you might be going too fast for the road conditions, even though you may be riding below the speed limit. It takes three-quarters of a second to make a decision to act once you see a hazard, and the same time again for the action to be effective.

At 60 km/h, you will have travelled 25 metres in that second and a half before you even start to brake. Riders who are tired, distracted or affected by alcohol or drugs will take much longer to react.

Riding at a speed where you have time to react to unexpected hazards will reduce your risk of a crash. Cars have four tyres in contact with the road and can stop much faster than motorcycles, so riders should always keep a three-second gap  from the vehicle in front.
