On a road wet with rain and with worn tires, both the free running (reaction) distance and the braking distance become at least twice as long.
Answer: ✕ False
Explanation
Road surface and tire condition affect the braking distance. The free running distance is determined by the driver's reaction time, so it does not change with road conditions. What lengthens the free running distance is fatigue or alcohol.

- On rainy days, visibility is poor and the braking distance is longer, so it is good practice to keep about twice the following distance you would keep on a clear day.
- On snowy or icy roads, it is good practice to keep a following distance about 3 times what you would keep on a clear day.
- A steep uphill slope is a place where you must slow down (to a speed at which the vehicle can stop immediately).
- Near a bend in the road, you must drive slowly enough to stop immediately, even when you have a clear view.
- On ordinary roads with a center line or marked lanes where no maximum speed is set by signs or markings, the statutory maximum speed for motor vehicles is 60 km/h.
- The statutory maximum speed for motorized bicycles (mopeds) is 30 km/h.
