About Bridge and tunnel: side wind, the bridge light, and the tunnel emergency procedures: which statement is correct?

At the bridge light you only need to stop if the red light is flashing, not if it is burning continuously (steady) red.
You may only switch on your dipped headlights once you actually enter the tunnel, not earlier.
✓ Because the wind also passes underneath, a bridge's road surface cools faster and freezes earlier than ordinary roads.
If your own car catches fire in a tunnel, your best option is to turn around or reverse to the nearest tunnel entrance.

Correct answer: Because the wind also passes underneath, a bridge's road surface cools faster and freezes earlier than ordinary roads.

Explanation

Because the wind also passes underneath, a bridge's road surface cools faster and freezes earlier than ordinary roads

'if that burns or starts flashing, you stop'. Steady red and flashing red both mean the same thing at the bridge light: stop
Dipped headlights must go on well before you enter the tunnel, precisely because drivers behind you might otherwise think you are braking if the light only comes on inside the tunnel
You never turn around and never reverse; you park close against the tunnel wall, leave the vehicle, and walk away from the fire via the nearest emergency exit
