Which TWO statements about driving in the rain are correct? Select TWO
When the road surface is wet from rain, you must drive at the maximum speed reduced by 20/100 (Article 19(2) of the Enforcement Rule). Think about whether braking distance gets longer or shorter on a wet surface, and what the road surface is like just after rain starts to fall.
Answer: ③, ④
Explanation
A wet road reduces the grip between tyres and road, so braking distance grows; slow down and increase your following distance. Article 19(2) of the Enforcement Rule requires driving at 20/100 below the maximum speed when the road is wet from rain. When rain first begins, dust and oil float up and the road is even more slippery. Working wipers do not restore the lost grip or visibility, so you must not drive at your usual speed.
