How Long Can a Car Run on the Highway in High Summer Temperatures?

[DeRyan]

It is best not to drive continuously on the highway for more than 3 hours in high summer temperatures. Problems that may arise from continuous highway driving: If a vehicle runs continuously for a day, it may experience cooling system issues, such as radiator blockages or water channel blockages, leading to overheating. For vehicles in poor condition, engine oil leaks may occur, and the leaked oil can continue to heat up as the vehicle keeps moving, increasing the risk of spontaneous combustion. After several hours of continuous driving, the vehicle's exhaust system may overheat, affecting engine performance. Precautions for summer driving: Do not drive in sandals or flip-flops; low tire pressure increases the risk of blowouts; take strict measures to prevent vehicle fires; avoid leaving lighters or perfumes in the car; and, most importantly, avoid fatigued driving during summer.
