Show the correct answer
Correct answer
A. 100 m.
Explanation
In the photo, you can see an expressway with noise barriers, and on the left the sign D-7 "expressway" above the sign for the end of a built-up area. On an expressway, you place the warning triangle 100 m behind the vehicle - answer A.
The Road Traffic Act requires you, on a motorway and an expressway, to mark in every case a vehicle that has stopped because of a breakdown or an accident, by switching on the hazard warning lights and placing a reflective warning triangle 100 m behind the vehicle, on the roadway or on the hard shoulder. The distance of 30-50 m (answer B) applies to roads outside built-up areas other than motorways and expressways, and 10 m (answer C) does not appear in the rules - in a built-up area you switch on the hazard warning lights, and you place the triangle behind the vehicle or on it, no higher than 1 m above the ground, when the vehicle has no hazard warning lights. On an expressway, cars travel fast, so a driver needs time to notice the obstacle and change lanes.
