Safe Lane Positioning - A frequent hazard to cyclists occurs when motorists pass and then abruptly turn right. This happens for various reasons. Drivers may underestimate a cyclist's speed or may be "asleep at the wheel." Regardless, it spells serious danger for cyclists. Fortunately, you can take measures to protect yourself. First, be especially cautious at intersections. If the lane is narrow and traffic is moving about your speed, take the entire lane, which lets followers know it's unsafe to pass. And, never assume that it's safe to pass a slow-moving line of cars on the right, because one might turn into you.
