   Show answer

   Answer: C. About 90% at 30 km/h, but only about 20% at 50 km/h

   Small speed differences make a huge difference to survival. This is why many towns use 30 km/h limits.

8. Question 8 of 25

   Traffic jams on a motorway with two lanes in your direction, in a country that requires an emergency corridor. You are in the left lane. Where do you move?

   • AOnto the hard shoulder
   • BTo the right
   • CAs far to the left as possible
   • DStay in the middle of your lane
   Show answer

   Answer: C. As far to the left as possible

   Vehicles in the far-left lane move left; all other lanes move right. This opens a corridor between them.

9. Question 9 of 25

   Why should you leave a bigger gap to the vehicle in front when the road is wet?

   • AWet roads make cars faster
   • BYour tyres have less grip, so you need more distance to stop
   • CSpray from your car could damage the car in front
   • DThe law requires exactly double in all countries
   Show answer

   Rain reduces tyre grip and makes braking harder, so stopping distances become longer.

10. Question 10 of 25

    What does this sign mean?

    • ACar park ahead
    • BOvertaking is never allowed again on this road
    • CNo overtaking for the next 2 km

    White end signs with black stripes cancel an earlier ban. You may overtake again when it is safe and legal.

11. Question 11 of 25

    What effect does low tyre pressure have?

    • AIt increases fuel use and can affect handling
    • BIt makes braking shorter
    • CIt reduces fuel use
    • DIt has no effect
    Show answer

    • DTalk to them calmly
    Show answer

    Answer: C. Remove their helmet

    If the rider is awake and breathing, leave the helmet on, because removing it can make a neck injury worse. If the rider is unconscious and you need to open the airway or start CPR, the helmet must be removed carefully, ideally by two people, as first aid courses teach.
