It’s important to check the hydraulic alarms before backing up to the flatbed

The driver was about to hook up the load, and he hooked it up as usual but was standing
at a slight angle, so he had to drive forward and try again. When the driver moved
the truck forward, the ground was so uneven that one of the hydraulic arms
caught on the gate of the flatbed trailer. The gate gives way, the walls come loose
, and the trailer tips over. It is extremely important to check the hydraulic arms before backing up
onto the flatbed.
