As temperatures rise during the summer, truckers are often exposed to dangerously hot conditions that can lead to heat-related illnesses — here’s what you need to know to protect your health in sweltering weather.

As temperatures climb into the 90s or triple digits, so does the risk to truck drivers of contracting heat related illness. Many truck drivers are lucky enough to have access to air conditioning in their vehicles while idling or using the APU, but some drivers end up sweating it out if they don’t have an APU or are in an area with strict idling rules. Some drivers are forced to park overnight in areas that aren’t safe and are afraid to even crack a window to let in a breeze.

Excessive heat can even have deadly consequences for drivers out on the road. In the summer of 2020, a 62 year old driver and his dog were found deceased in a hot truck at a truck stop in Barstow, California.
