Its very "teaching Grandmother to suck eggs" but here you go, apparently you don't need grab bars or steps, an we probably do it without thinking anyway.

Entering and Exiting Vehicles Safely

Truckers, delivery drivers, farmers, firemen, and workers that drive or ride in large commercial trucks and vans, farm equipment, and fire apparatus get injured when they enter and exit vehicles unsafely. Due to inattention, speed, and rushing in an emergency, workers slip and fall when they do not use vehicle steps and handhold devices. Jumps and falls cause ergonomic strains and sprains, broken bones, and fatalities.

If you work around large vehicles, wear shoes with sturdy, no-slip soles and a heel. Clean and maintain the vehicle steps; wet or oily “diamond plate” can be very slippery. Only climb on dedicated stepping areas; fuel tanks and fenders can be slippery. In hot and cold weather, wear gloves to help you grip hand railings.

When you enter a vehicle, face it. Take hold of the grab bar and use it to help you climb up. If a grab bar is not available, grip the seat or other fixed object in the vehicle. Don’t grab the steering wheel unless it is “locked;” it can turn suddenly and throw you off balance. Don’t grab the door or handle because it can swing out and cause you to fall. If grab bars are missing or improperly placed, add one or move it to a safer location.

Plan your steps into the vehicle so that you are standing on the same leg as the side that you are entering. To enter the driver’s side, stand on your left leg and lift your right leg up. You may need to change hand and feet positions while entering and exiting. Keep three points of contact with the vehicle at all times (one hand and two feet, or two hands and one foot). To avoid falling out backwards, maintain the three point rule until you are securely seated or firmly on the ground.

To exit the vehicle, examine the ground before you step out. Look for ice, water, cracks, and uneven surfaces. Face the vehicle and step down backward while holding onto the grab bar or other stable surface. Use all of the steps until you reach the ground. Don’t use some of the stairs, then jump and hurt yourself by skipping one. Never jump down or "fall" down forward out of a vehicle; you can catch your clothing on the door handle, seat adjustments, seat belt, etc. causing a serious, uncontrolled fall.

Jumping increases the force and strain on your bones and joints (mostly ankle, knee, and back). For example, in a cab-over-engine tractor, jumping from the top step can apply 7.1 times your body weight to your back and leg joints (1420 pounds of force for a 200 pound man). Jumping from a delivery step-van with a package in hand causes an impact of 3.5 times the body weight plus package weight. Add these impacts to frequent entries and exits and you are at risk for an ergonomic injury. Climbing down safely can save you pain and time in the long run.
