What are the signs?
You might suspect the other driver is uninsured or drunk if:
They refuse to share insurance details
They appear confused, aggressive, or impaired
They attempt to leave quickly
Their vehicle has no number plate or MOT disc (if visible)
What should I do at the scene?
Call 999 immediately if someone appears to be under the influence or if there’s a risk to safety.
Call 101 if it’s not an emergency but you suspect illegal driving (e.g. no insurance).
Take note of:
Their registration number
Make/model of their vehicle
Time and location
Their behaviour and any comments made
Do not confront them – Your safety comes first.
Ask witnesses for contact details if possible.
