Motoring experts at the RAC have issued an urgent reminder to all drivers about the critical dashboard warning lights that must never be ignored. The advice, shared widely on social media, aims to help motorists "avoid a headache" and potentially dangerous situations by understanding their vehicle's alerts.
The Colour-Coded Warning System
In a guide posted to its TikTok channel on 12 January 2026, the RAC explained that dashboard warning lights follow a simple but vital colour system. Yellow or amber lights are cautionary, indicating a problem that needs attention. Red lights, however, signal an urgent issue that requires immediate action.
The organisation advised that if a yellow warning light illuminates, drivers should take extra care, consult their vehicle handbook, and arrange for a mechanic to look at the problem as soon as possible. For a red light, the instruction is clear: pull over safely and stop driving.
How to Respond to Different Alerts
The RAC's specific guidance breaks down the recommended steps based on the alert's severity. For a cautionary yellow light, they suggest calling on their RAC Mobile Mechanic service. When faced with a serious red warning, drivers should report a breakdown immediately via the myRAC app or service.
It is normal for several lights to flash on briefly when you start your car's engine. The concern arises when one or more lights remain illuminated. The RAC recommends treating these persistent warnings with a traffic light mentality:
- Red: Indicates a serious, potentially dangerous fault. Stop the car when safe and seek professional help immediately.
- Yellow/Orange: Signifies a problem that needs checking but is less urgent. Proceed with extra caution and have it investigated soon.
- Green/White/Blue: Shows a system is working correctly or is currently in operation.
Staying Prepared on the Road
The plethora of symbols on a modern dashboard can be confusing, but their purpose is singular: to inform you of a potential issue with your vehicle. The RAC stresses that acting on these warnings is crucial for safety and to prevent more extensive damage.
They also emphasise the importance of having adequate breakdown cover. For those travelling abroad, it is worth checking if your policy, whether through the RAC or another provider, offers European cover.
By understanding this simple colour code and knowing how to react, drivers can make informed decisions, ensuring their safety and potentially avoiding costly repairs down the line.
