You are approaching the Velsertunnel. It is still full daylight outside and you are wearing sunglasses. What do you do?
Dipped headlights on well before the tunnel, I keep my sunglasses on
Sunglasses off, dipped headlights only once I enter the tunnel
Dipped headlights on well before the tunnel and sunglasses off
Explanation
False — you switch the lights on too late. Switch on dipped headlights well before the tunnel; if they only come on inside, drivers behind think you are braking (Book p.99).
