There are a few tips that truck drivers, or anyone operating a vehicle with a trailer attached, can observe to avoid jackknifing. Always allow plenty of space between your vehicle and the vehicle in front of you. Leave extra space between vehicles for braking in bad weather conditions like snow, ice, or rain. Be especially mindful if carrying light loads or loads with poor weight distribution. Avoid braking excessively while navigating curves. If at all possible, avoid swerving and braking at the same time. Always have your equipment properly maintained and repaired.
