Turn left from the left turn lane. Do not pass on the right. Motorists may not look for or see a bicycle passing on the right. Scan the road behind. Learn to look back over your shoulder without losing your balance or swerving.
Some riders use rear-view mirrors.
Avoid road hazards. Watch out for gravel, ice, or debris. Be ready to brake at all times. Allow extra distance for stopping in the rain, since brakes are less efficient when wet. Use lights at night or when visibility is low.
