The RAC urges motorists to postpone non-essential journeys as a record heatwave brings unusually high temperatures that could damage road surfaces. The warning highlights concerns that extreme heat may soften or deform roads, increasing the risk of hazards for drivers. Alongside the threat to road conditions, the RAC also warns that very hot weather is likely to lead to more vehicle problems and breakdowns. The guidance is framed as a caution to reduce travel until conditions improve, rather than a blanket travel ban. Drivers are encouraged to avoid trips that are not necessary and to take account of changing conditions if they must travel. The reports focus on the same overall message: extreme temperatures are expected to affect both infrastructure and vehicle reliability. Motorists are urged to plan carefully, remain alert to road and traffic conditions, and limit time on the road where possible.
