The Tennessee Commercial Driver License Manual emphasizes that safe drivers must manage the space ahead, behind, beside, and above their vehicles. Space gives professional drivers time to recognize hazards and react before a collision occurs. According to the CDL Manual, the area in front of the truck is the most critical because rear-end collisions often occur when commercial vehicles follow traffic too closely. The manual recommends maintaining at least one second of following distance for every 10 feet of vehicle length at speeds below 40 mph, with an additional second at higher speeds. Drivers should increase that distance even more during rain, fog, or other hazardous conditions.

Managing space also means avoiding prolonged travel in another vehicle’s blind spot, checking mirrors frequently, allowing room for vehicles entering the roadway, and leaving enough space when making turns or changing lanes. These are not merely good driving habits—they are fundamental safety practices expected of every professional truck driver.

Unfortunately, when drivers are under pressure to meet delivery deadlines or are distracted, these basic principles are sometimes ignored. Following too closely, unsafe lane changes, and failing to maintain a safe buffer around a commercial vehicle can result in devastating crashes that cause life-changing injuries.

At The Hamilton Firm, we regularly investigate serious truck accidents to determine whether a driver’s failure to properly manage space contributed to the collision. Driver training, electronic logging data, dash camera footage, and other evidence can reveal whether a crash could have been prevented by simply maintaining a safe distance.

Sometimes, a few extra seconds—and a little more space—can make all the difference.
