JJ Keller Entry Level Driver Training for CDL (Commercial Driver’s License) Practice Test

When navigating off-ramps, commercial motor vehicles (CMVs) are typically advised to drive at a speed that is 5 mph less than the designated ramp speed limit. This recommendation is in place primarily to ensure safety. Off-ramps often feature curves and varying inclines, which can present challenges to larger vehicles that require longer stopping distances. Reducing speed helps maintain better control of the vehicle, minimizes the risk of tipping over, especially when turning, and allows for a safer transition from highway speeds to lower speeds on surface streets.

Additionally, CMVs are usually heavier and may not respond as quickly to steering inputs as smaller vehicles. Therefore, driving below the speed limit on off-ramps helps accommodate these factors, enhancing the safety of the driver, cargo, and other road users. The additional margin provides a buffer against unexpected obstacles or hazards that may arise as the vehicle exits the highway.
