Make your intentions clear to everyone on the road. Ride in a straight line, as far to the right as possible, and don't swerve between parked cars. Signal turns in advance, and check your surroundings before turning or changing lanes.
Make yourself seen by riding in well-lit areas and wearing bright clothing. Use a front white light, red rear light, and reflectors when visibility is poor.
Check that your tires have enough air, brakes are working, and chain the runs smoothly to minimize breakdowns. Always make certain that your helmet fits properly and is secure before starting your ride.
