noticed the red X
signal when driving on
It’s there for your safety and it’s illegal to ignore it.
The red X sign is key to supporting safety on motorways. It tells you a lane is closed, either to protect drivers in difficulty, or when road workers and emergency services need a space to work.
Most drivers respect the red X signal. But those who don’t put themselves and other road users at real risk.
red X and
all signals set
The illustrations below show a typical sequence of signs and signals you’ll see on the motorway when a red X signal is set. This helps to manage incidents or accidents.
Sometimes a red X signal needs to be set far in advance of an incident to provide access for emergency services. Or to help you re-join the motorway from an emergency area. When you see the red X, it means the lane is closed and you must not use it.
Please leave gaps in the traffic to let other drivers move into an open lane.
Signs will also show when the lane is re-opened. You may see a national or variable speed limit, or a message informing you of the end of the restriction. Do not move into a closed lane even if you’ve passed a hazard, as there may be other hazards up ahead in the same lane.
