The AA has issued an urgent warning that gritting lorries will be seen on UK roads this week, not for snow or ice, but to protect tarmac from melting during an extreme heatwave. The Met Office has forecast temperatures reaching up to 40°C in over 50 areas, including London, Birmingham, and parts of the Midlands, prompting the unusual measure.
Why Gritters Are Being Used in Summer
Typically associated with winter, gritting lorries will spread grit to prevent road surfaces from softening or becoming sticky under the scorching heat. Heavy traffic could cause ruts in the tarmac, posing risks to drivers. Edmund King, AA president, stated: "The main risk for drivers is not that the road suddenly 'melts' everywhere, but that patches can become tacky or uneven. That can affect braking, steering and grip, especially for motorcyclists and cyclists, and can also throw up loose material."
Advice for Drivers
The AA advises drivers to slow down, avoid harsh braking or steering, and leave extra space from the vehicle in front if they encounter softened or damaged surfaces. Mr. King also warned that heat can strain vehicles, with under-inflated, damaged, or old tires particularly likely to fail. He said: "Before a long journey, check tyre pressures, tread and sidewalls, and carry water in case you are delayed. In these temperatures the advice remains never to leave passengers or animals unattended in parked cars even for short periods when the interior of the car can soon get as hot as an oven."
Met Office Weather Warnings
The Met Office has issued a rare red weather warning for 50 UK areas, effective from 9am on Wednesday, with an amber warning for Wednesday and Thursday. The forecast states: "Temperatures will quickly rise on Monday and are forecast to reach 34°C in southern parts of England. The heat will build further into Tuesday, with highs of 37°C forecast for southern England and 35°C in southeast Wales. The peak of the heatwave is now forecast for Wednesday and Thursday, when temperatures are expected to climb to at least 39°C and there remains a chance of this being exceeded in places."
Impact on Roads and Traffic
The AA's warning comes as the UK braces for potentially record-breaking temperatures. Motorists should be prepared for gritters on roads and possible disruptions due to road surface damage. The combination of extreme heat and heavy traffic could lead to hazardous conditions, particularly on busy routes.
