Follow the rules of the road. Obey traffic signs and signals and markings.
Do a pre-ride check. Check for any signs of damage or punctures, test brakes, and if riding at night that lights work.
Be Predictable. Ride at a steady pace and do not make unexpected turns and do not swerve in and out of traffic. When turning give clear hand signals in advance to let drivers and cyclists know what you are doing. Be aware of other road users around you
