ROAD SAFETY TIPS
SAFE RIDING
1. Before riding, you should learn to ride your motorcycle properly and all the control functions should be known
to you.
2. Remember that there are no legal “rights” when it comes to survival as far as Motorcyclists are
concerned. The fact that you may be well within your rights is no guarantee that you will avoid a collision with
a bigger vehicle whose driver fails to see you. Always ride defensively and take nothing on road for granted.
3. Develop the ability to react swiftly to any unexpected road hazards or emergencies giving yourself time to
spare for appropriate response.
4. Develop the ability to get the most out of your Motorcycle, But at the same time get to know its capabili-
ties and limitations.
5. Ride thoughtfully, planning your route well in advance.
6.Give proper Signals and use Horn and Headlights judiciously.
7. Don’t ride in another motorist’s blind spot.
8. Always make pre-ride safety checks before you start the Engine.
SAFE BRAKING
Use the basic methods of braking effectively.
1. Engine Brake : When the Throttle is released, compression backs up and acts as the Engine Brake.
If the riding condition allows, reduce speed by shifting the Gear down.
2. Front and Rear Brakes : It is important to apply equal force to the Front and Rear Brakes simultaneously.
• Use Front and Rear Brakes simultaneously.
• Be sure not to disengage the clutch while braking.
• While riding downhill always use Engine as a Brake and never ride in Neutral Gear.
• While riding down hill do not switch off ignition while Engine is in gear. CAUTION :
