Undertaking driving fine UK rules: what the £100 penalty covers
The £100 fine for careless driving dates from 2013 and can apply to poor lane discipline. A parliamentary petition asking for undertaking to be decriminalised drew only 42 signatures.
Key points
- The £100 fixed penalty and 3 points apply to careless driving, including poor lane discipline, under rules in force since 16 August 2013.
- A petition on middle lane hogging and undertaking closed with 42 signatures, well short of the 10,000 needed for a government response.
- None of the sources reviewed contains new police guidance on undertaking, and none names a specific undertaking fine.
- The Highway Code sections on overtaking, motorway lane discipline and penalties are where the detailed rules sit.

The sources support a modest conclusion: drivers are being left to guess. A £100 and three-point penalty exists for careless lane discipline, but nothing we reviewed says plainly how undertaking is treated, and the one petition on the subject drew 42 signatures. Anyone promising certainty about a specific undertaking fine is going beyond the evidence. If police want drivers to follow the rules, they should publish the guidance in plain terms, not leave it to rumour.
