**Wales Drivers Urged to Follow Vital Highway Code Rule Amid Sweltering Heatwave**
As Wales grapples with an intense heatwave and rising temperatures, motorists are being reminded of crucial safety measures that must be observed behind the wheel. Concerns over heatstroke have surged, and experts are urging drivers to take heed—not only for their own well-being, but also in accordance with legal requirements.
Car interiors can become dangerously hot in a matter of minutes, often far exceeding the temperature outside even when windows are slightly open. Graham Conway, managing director of Select Car Leasing, emphasised the risk, warning: “People may underestimate just how quickly temperatures inside a car can soar. Even short journeys can turn perilous in the current climate.”
Public awareness of heatstroke has increased dramatically, with recent searches for information on the condition rising more than 185 percent in the past month, reflecting growing anxiety as temperatures climb. Heatstroke is a life-threatening emergency, particularly hazardous for those driving long distances or stuck in stationary traffic, where ventilation may be limited.
The Highway Code directly addresses this risk under Rule 237, which requires drivers to keep their vehicles well-ventilated to avoid drowsiness. Ignoring this rule does not only put lives at risk but may also have significant legal consequences. Failure to comply could be deemed careless driving, leading to unlimited fines and up to nine points on one’s driving licence if prosecuted.
Mr Conway additionally underscored the importance of staying hydrated, pointing out NHS guidelines recommending between six to eight glasses of water a day. “Some motorists may reduce their fluid intake on long journeys just to avoid making pit stops, but this could have disastrous effects. The body’s cooling mechanism—sweating—cannot function properly if you are dehydrated, especially inside a stuffy vehicle,” he explained.
The symptoms of heatstroke often come on rapidly. These can include headache, dizziness, cramps, nausea, and overwhelming fatigue. Once a driver’s concentration wavers due to these symptoms, their capacity to react swiftly and appropriately on the road is severely diminished—increasing the chance of incidents.
In practical terms, drivers are advised to open all windows when first entering their vehicles to release the trapped heat, before settling on a comfortable method of cooling, such as air conditioning or opening windows slightly while on the move. However, Mr Conway noted that relying on the air recirculation feature for prolonged periods can reduce oxygen in the car, which may itself cause drowsiness. Alternating between fresh air and recirculation modes when in traffic could be beneficial.
Preparation is also key for those spending extended periods in their cars. Motorists should stock up on water before setting off, and opt for lighter clothing that will help the body regulate heat more efficiently. Carrying a bottle of water for each occupant and wearing breathable fabrics can make a significant difference.
In the event that any symptoms of heat exhaustion or heatstroke do develop while driving, drivers are urged not to press on. The safest course of action is to pull over as soon as it is safe to do so, switch off the engine, move into the shade, and rehydrate until feeling well enough to continue.
With weather forecasts predicting continued high temperatures across Wales, authorities and motoring experts alike are reiterating that vigilance could save lives. Adhering to the Highway Code and practising common sense measures might make all the difference this summer for drivers and their passengers alike.
