SACRAMENTO, Calif. — Today's Why Guy question relates to Sacramento's recent surge in cycling usage.

"I just read some of the 2019 DMV rules, and one of these rules stated a $299 fine for driving too slow. With that info in mind, why are bicycles allowed on narrow 2 lane roads?"

Ok, let's jump on a bike and go for a ride since this seems to be about bicycles slowing vehicle traffic. If the speed limit is about 30 miles per hour in congested areas, one can expect bicycles to be at or near the speed of motor vehicles and can legally ride in the lane you're driving in.

"Bicyclists are permitted to use the full lane when driving at the speed of traffic....and pull off the roadway when a rider has five or more vehicles lined up behind them," CHP Officer Mike Harris said.

Most recreational cyclists are generally pedaling at a max of 30 mph, so once the speed limit gets higher, cyclists are required to pull over to the right, as far as possible, and keep moving. The old saying of "it's a two way street" works for both cyclists and cars. 

"The driver of a motor vehicle must give at least three feet of clearance when passing a bicycle or slow to a reasonable speed and pass only when doing so would not endanger the safety of the bicyclist," Harris said.

So, the rules of the road apply to both: don't create a backup, yield appropriately at intersections and driveways, and obey all traffic signs and signals. If you’re riding a bike and not moving at the speed of motor traffic, pull over. Find the bike lane. Ride safe!
