Blood pressure plays a critical role in passing the Department of Transportation (DOT) medical exam required for commercial drivers. This guide explains the DOT blood pressure standards, why high blood pressure is common in trucking, and practical steps drivers can take to manage their health, stay medically qualified, and maintain safe performance on the road.

Truck driver fatigue rarely appears all at once. It usually builds slowly through long driving hours, disrupted sleep schedules, dehydration, and daily stress on the road.
