What it means
Temporary Warning: A police presence or checkpoint is ahead. Slow down and be prepared to stop for inspection.
What to do
- Slow down and prepare to stop for a checkpoint or roadblock.
- Follow hand signals from officers; they override lights and signs.
- Have your licence ready if you are directed to pull over.
In the K53 test
The flashing-light symbol warns of a police presence ahead. Officer instructions at the checkpoint rank above every other sign or signal, and failing to stop when directed is a serious offence.
Where you will see it
On any road where temporary police flashing-light control or warning is in use.
