The AA has issued a stark warning to motorists across the UK, cautioning that the combination of scorching temperatures, dehydration, and sleep deprivation is creating a heightened risk of road rage and driving errors comparable to being under the influence of alcohol or drugs. The alert comes as the Met Office has issued Red and Amber heat warnings across parts of Britain, with temperatures expected to soar between 38°C and 40°C in the hottest regions, and stifling nights disrupting proper rest.
Fatigue and Dehydration Impair Driving Performance
The motoring body highlighted that fatigue can impair reaction speeds and diminish focus, making typical annoyances like traffic jams, hold-ups, and discourteous driving more challenging to tolerate. The AA referenced studies from DriveTech, its driver education arm, showing that dehydrated motorists can commit as many blunders at the wheel as those driving under the influence of alcohol or drugs. Dehydration can also trigger exhaustion, reduced concentration, weakened short-term memory, and slower reaction times, according to the organisation.
The AA cautioned that the irritability brought on by sweltering heat and congested roads can spill over into dangerous driving behaviours such as tailgating, harsh braking, speeding, and reckless overtaking. Motorists who begin to feel drowsy have been advised to pull over somewhere safe and take a proper rest, while those too fatigued to drive should postpone their journey where possible.
Expert Advice for Staying Safe on the Roads
Edmund King, president of the AA, said: "Hot weather, heavy traffic and tired drivers are not a good mix. If people have struggled to sleep in the heat, they may be less patient, less focused and more likely to make mistakes on the morning commute. DriveTech, the driver training arm of The AA, has highlighted how dehydration can seriously affect driver performance in a similar way to drink or drugs. In this heat, keeping water in the car is not just about comfort, it is about safety."
King added: "Road rage can escalate quickly, especially when people are uncomfortable and rushing. Stay calm, avoid reacting to other drivers, keep a safe distance and remember that everyone else is dealing with the same heat. If you feel too tired to drive, delay your journey if you can. If you start to feel drowsy behind the wheel, stop somewhere safe and take a proper break."
Drivers are being advised to keep well-hydrated, factor in additional travel time, and resist responding to provocations from fellow road users to ensure safety during the extreme heatwave conditions.
