Companies such as Lytx and SmartDrive sell truck video systems to capture accidents a well as driver performance while on the road. Trucking companies that use these products may have better safety stats, but they certainly don’t have happier drivers.

However, driver cams are often turned on or off depending on the driver’s performance. Actions such as hard braking, swerving and other unsafe behaviors trigger the in-cab camera to turn on. Also, one of the new features in Lytx systems is that fleet owners will have the option of rewarding safe drivers by turning off the in-cab cam while leaving just the forward-view camera operational.

In either case, having a camera pointed at your face during long working hours is always unnerving, even if you’re an excellent driver with dashing good looks and a narcissistic personality.
