In California, drivers may enter a bike lane only within the final 200 feet before an intersection to prepare for a right turn. If you’re approaching a corner in Los Angeles or anywhere in the state and there’s a bike lane hugging the curb, that final approach is the only place where merging is allowed. You merge as you would into any rightmost traffic lane, signal, and then complete your right turn from that lane. Drifting across at the last moment from the next vehicle lane is exactly how right-hook crashes happen.
Drivers see dashed bike lane markings near the corner and assume they’re optional. They’re not decoration; they indicate where it is legal to move over. Used correctly, bike lanes and turn lanes reduce conflict between cars and bicycles moving in the same direction. Used incorrectly, they put cyclists and drivers in each other’s blind spots.
When does California law allow drivers to enter a bike lane for a right turn?
The California Vehicle Code treats a bike lane as part of the roadway and, in that last approach to a corner, as the rightmost car lane you should use to turn. CVC §21209 is the 200-foot rule: motor vehicles may drive in a bicycle lane only to park where permitted, to enter or leave a driveway or roadway, or to prepare for a right turn within 200 feet of the intersection. That short stretch is the legal merge zone. You’re still required to look, signal, and yield.
On the street, this looks like a calm, predictable movement. You watch the dashed line, click your turn signal, check the right mirror and your shoulder for a cyclist present, and then glide into the lane before you reach the corner. You do not try to pass bikes here. You slow slightly, hold a straight line, and finish the right hand turn from the lane nearest the curb. If a rider is continuing straight, you wait. Their path is the straight line through the intersection; yours is a turn across it.
Traffic lights do not change the priority. A green light allows a movement but does not erase the cyclist’s right of way. A red light allows a right turn where permitted, after a complete stop, but you still must yield to pedestrians in the crosswalk and to bicycle riders traveling through. The safest way is always the same: merge early, be visible, and never cut across.
What California Vehicle Code Section 21717 says about merging into bike lanes
CVC §21717 answers the heart of the question “at what point can you enter the bike lane to make a right turn?” It says that when you need to cross a bicycle lane to turn, you must first drive into that lane and then make the turn pursuant to §22100. In other words, enter the bike lane before you turn, not during the turn.
Read together, these sections make a clean sequence:
- §21209 limits where you can be in the bicycle lane: within 200 feet of the corner to prepare for your right turn or when crossing to a driveway.
- §21717 requires how you do it: by merging into the lane first, not slicing across it.
- §22100 tells you from where to turn: as close as practicable to the far right edge of the roadway, which, on a street with a bike lane, means from that designated lane by the curb.
- §22107 adds the safety standard: no turning until it can be made with reasonable safety, and only after giving a signal.
- §21658(a) covers the lane discipline everyone forgets: stay within your lane and don’t move from it until the movement can be made safely.
There are streets where the bicycle facility is separated from motor vehicles with posts, parked cars, or a raised curb for the exclusive use of bikes. In those locations, motorists do not merge into the bikeway at all. You follow the posted right turn lane or the turn pocket and cross where the design and signals allow. Local ordinances and intersection designs in each city can add signs or bike signals that control the exact timing.
Common mistakes drivers make when entering bicycle lanes to turn right
Most problems come down to timing and awareness.
“We see the same pattern after serious bike crashes,” says Sasha Bojat, founding attorney of Bojat Law Group. “A driver thought the bike lane was empty or believed they could turn from the vehicle lane without merging. The code is clear. Enter the bike lane near the corner, signal, and yield. That predictability is what keeps everyone upright.”
The first mistake is entering too early and driving a long stretch in the bike lane as if it were another vehicle lane; it isn’t. The second is the last-moment dive from the next lane across a rider’s path. That move creates a side impact with a cyclist you never fully saw, and it’s the textbook right-hook collision.
Another frequent error is treating the bike lane as a waiting area. When drivers park themselves in the lane far from the corner, cyclists must leave their protected space and filter into faster motor vehicles in the center lane. It’s predictable, and it’s wrong. If traffic is backed up through the block, you hold your position in the car lane until you reach that merge area, then you enter the bike lane and wait there close to the corner. Your wheels stay pointed straight.
Paint can vary by city, which confuses people. A solid white line tells you not to merge. A dashed line near the corner means you may safely merge there if clear. Some agencies drop the line completely in the last segment to emphasize the merge. The law doesn’t change with the paint; the rule is the same: merge within about 200 feet, signal, check, yield.
And finally, respect the human being riding next to you. Bikes accelerate differently, take different lines through a corner, and can be hidden behind your A-pillar. If a cyclist is alongside after you’ve merged, you simply wait. Drivers pass bikes where appropriate, not inside the merge zone. The few seconds you give up will always be less costly than a crash.
The safest way to merge into the bike lane
- Scan ahead. Identify the corner, the bike lane markings, and the merge section.
- Signal right about 100 feet before you move.
- Mirror, shoulder check, and reduce speed.
- When clear, gently merge into the bike lane within that last 200 feet.
- Keep the bike lane speed slow. Do not try to pass cyclists here.
- Yield to riders and pedestrians, then complete a smooth right hand turn close to the curb.
- After turning, center your car in the new lane and match the flow of traffic.
Injured in a bike-lane right turn crash?
If you were injured because a driver turned right across a bicycle lane without entering the lane in the final 200 feet and without yielding to a cyclist traveling straight, your claim should be evaluated against the applicable California Vehicle Code and the specific conditions at that intersection.
