Follow lane markings. Stop at all stop signs and red lights. If two vehicles arrive at an intersection at the same time, the vehicle to the right has the right of way. Politely indicate others' right of way with a hand gesture. For your own safety, never insist on your own right of way.
Pedestrians always have the right of way.
Your courtesy will be noticed and appreciated by other road users. Generally, it is prudent to stay as far to the right as practicable. When riding with others, do not block traffic, ride single file. Be aware of other road users at all times. When stopping for a stop sign in a group, queue up in small numbers and proceed when it is your turn, allowing other road users their right of way.
