About Bridge and tunnel: side wind, the bridge light, and the tunnel emergency procedures: which statement is correct?
'if that burns or starts flashing, you stop'. Steady red and flashing red both mean the same thing at the bridge light: stop.
Bridges and viaducts only become slippery in frost at the same moment as the rest of the road, not earlier.
In case of breakdown in a tunnel you may cross the carriageway if the nearest emergency post is on the other side.
If your own car catches fire in a tunnel, your best option is to turn around or reverse to the nearest tunnel entrance.
Explanation
trap: signal state read too strictly. Book p.97 - 'if that burns or starts flashing, you stop'. Steady red and flashing red both mean the same thing at the bridge light: stop
