Show the correct answer
Correct answer
C. C.
Explanation
In the drawing, three symbols: A - a red double triangle, B - green lamps with rays to the sides, C - a blue headlamp with horizontal lines. When light C comes on, it means that main beam (high beam) is switched on - answer C.
The main beam warning light is blue - this colour is meant to catch your attention, because these lights can dazzle others. The horizontal lines stand for a beam shining straight ahead and far; in the dipped headlights (low beam) symbol the lines slope downwards, and the warning light is green. Symbol A is hazard warning lights, and symbol B - sidelights (position lights). You may use main beam from dusk to dawn on unlit roads, as long as you do not dazzle others. You switch to dipped headlights when a vehicle is approaching from the opposite direction, when you are catching up with another vehicle, and also when a rail vehicle is travelling so close that you could dazzle its driver.
