New Operator Driving Procedures 

13. Apply the brakes and shift into gear.
14. Release the parking brake.
15. Check your surroundings. Make sure the area is clear of people 

and obstacles.

16. Keeping both hands on the steering wheel, slowly release the 

brakes and press the throttle with your right foot to begin driving.

17. Drive slowly at first. Practice starting, stopping, turning, using the 

throttle and brakes and driving in reverse. Learn how the vehicle 

handles when making both left and right turns at a slow speed.

18. Increase speed only after mastering all maneuvers at a slow speed.
19. After you become skilled at making turns and begin to operate at 

faster speeds, follow these precautions:

• Avoid sharp turns. Make turns gradually.
• Never turn while applying heavy throttle.
• Never turn the steering wheel abruptly.
• Operate at speeds appropriate for your skills, the conditions and 

the terrain.

• DO NOT attempt to do power slides, “donuts”, jumps or other 

driving stunts.
