Rule 279: Disabled drivers
Disabled drivers. If you have a disability that prevents you from following the above advice in Rules 277 and 278, you should
- switch on your hazard warning lights
- stay in your vehicle and keep your seat belt on
- call 999 immediately and ask for the police. Alternatively, press your SOS button if your vehicle has one and ask for the police.
If you are deaf, hard of hearing or speech impaired, it is recommended that you register for the 999 text service (emergencySMS.net) before making a journey.
Advice, not law. This rule is not written in capitals, so breaking it is not an offence in itself — but it can still be used in evidence in court to establish liability. The rules that say MUST or MUST NOT are the ones backed by law.
