Short answer: a right hook happens when a driver turns right across the path of a cyclist who is going straight, and the rider hits the side of the turning car. The League of American Bicyclists advises against riding on the right side of a right-turn lane when you are not turning, and says motorists "are not looking for other vehicles there." The City of Menlo Park advises riders to watch for the car's right-turn signal and to avoid the car's blind spot. California law tells drivers to move into the bike lane before turning, but a legal duty does not mean the driver has seen you.
If your reaction to this topic is "the driver just turned straight into me," or you fear it will happen, the useful question is how to be somewhere a turning driver will see you before the turn begins.

Where Bicyclist Deaths Actually Happen
The title promises the truth about where crashes happen, so here is what the national data says and what it does not. The Pedestrian and Bicycle Information Center (PBIC), which compiles NHTSA crash data, reports these figures for bicyclist fatalities from 2019 to 2023:
- 62.7% occurred at non-intersections.
- In urban areas, 47.8% occurred at non-intersections and 33.5% at intersections.
- In rural areas, 14.6% occurred at non-intersections and 3.5% at intersections.
- 49.7% occurred in dark conditions.
Two things follow. First, most deaths in this data happen between intersections, so it would be wrong to say intersections are where most fatal crashes occur. Second, about a third of the bicyclist deaths in the data were at urban intersections, which are small spots compared with the stretches between them. That concentration is why they deserve attention.
The limits matter too. These are fatalities, not all crashes, and we did not find a source for the share of non-fatal injury crashes at intersections that we could verify, so we do not quote one. PBIC also notes that "7-46 percent of bicyclist crashes may be missing from police-reported crash data." Use the numbers to see where the worst outcomes occur, not to predict your own ride.
What a Right Hook Is
The City of Menlo Park, California, describes a right hook in its guide to avoiding right hook collisions as a situation in which "a bicyclist collides into the side of a turning car," where drivers cut across bike lanes while turning right at intersections.
It can look like either of two things:
- A car overtakes you and turns right in front of you, because the driver did not account for you coming up behind.
- A car beside you, or already ahead of you, turns right across your path while you continue straight.
In both cases you are on the right, going straight, and the driver is turning across you. The person in the car may not have seen you at all, and the danger is highest where your position is in the blind spot to the right of the vehicle.
What the Law Says Drivers Must Do
California's Vehicle Code 21717 says: "Whenever it is necessary for the driver of a motor vehicle to cross a bicycle lane that is adjacent to his lane of travel to make a turn, the driver shall drive the motor vehicle into the bicycle lane prior to making the turn and shall make the turn pursuant to Section 22100."
Menlo Park describes the same duty in practice: drivers should turn on their signal, check for bicyclists in the bike lane, and merge into the bike lane as they approach the intersection before completing the turn.
That is the law in one state. Other states set the rules differently, and your city may have its own. Even where the duty is clear, it is not a guarantee. Andrew Phillips, who writes as "The Cyclist Lawyer" for Cycling West in Utah, puts it this way in his piece on avoiding the right hook: "Even though you have the right of way, does not mean the motorist will respect your space or that they have even seen you."
Where to Ride Near an Intersection
The sources agree on a short set of positions:
- Stay out of the blind spot. Menlo Park advises riders to "be on alert for the car's right-turn signal and avoid traveling in the car's blind spot."
- Do not ride on the right of a car approaching a turn. The League says: "Do not ride on the right; motorists are not looking for other vehicles there."
- Avoid the right side of a right-turn lane if you are not turning. The League's guidance is to avoid "lanes that position you on the right side of a right turn lane" when you are going straight.
- Take the lane before the intersection when it applies. The League advises taking the lane "before intersections and turns to assert your position on the roadway," and "so you don't get forced to the right of a stopped car."
- If a car is already in the bike lane ahead of you waiting to turn, Menlo Park says to "pass the car on the left or wait for it to complete its turn before continuing on."
Each of these shares one idea. The decision is made before the intersection. By the time a turning car is beside you, there is no good option left.
A Quick Reference by Situation
| Situation | What the sources describe |
|---|---|
| A car is beside you as you approach the intersection, with its right signal on | Avoid its blind spot and do not ride on its right (Menlo Park, League) |
| A car in the bike lane ahead is waiting to turn right | Wait for the turn to finish or pass on the left (Menlo Park) |
| A right-turn lane appears and you are going straight | Avoid the right side of that lane (League) |
| You are approaching an intersection with traffic around you | Take the lane before the intersection to assert your position (League) |
| You are about to turn and there is a stopped car ahead | Take the lane so you are not forced to the right of it (League) |
| You are looking at your destination lane | Check for obstacles there, such as a double parked car (League) |
Reading the Driver
A signal is one clue, not a guarantee. Menlo Park advises riders to be on alert for the right-turn signal, but a car with no signal can still turn. The things worth noticing before the intersection:
- Is the car slowing as it nears the corner?
- Is it drifting toward the right edge or into the bike lane?
- Is the driver looking toward the right, toward the crosswalk or side street?
These are observations, not guarantees. If anything points to a turn, the safer reading is that the car is turning. The sources recommend positions that make the driver's decision easier, not ones that rely on the driver's attention.
Light, Weather and Visibility
Right hooks are partly a visibility problem. A rider who is hard to see is easier to miss. Our fall cycling tips cover lights and reflective gear as the evening commute moves into the dark, which matters here because PBIC reports that 49.7% of bicyclist fatalities from 2019 to 2023 occurred in dark conditions, with the hours from 6 p.m. to 11 p.m. standing out.
Wet pavement lengthens your stopping distance when a car turns across you, so a rain commute needs more room than a dry one. Our guide to bike braking in the wet explains what changes.
Learning It Without Learning It the Hard Way
Reading about a right hook is not the same as spotting one in motion. If intersections worry you, a few steps are low risk:
- Observe from the sidewalk. Watch how cars behave at a local intersection with a bike lane and see how often turning drivers signal and check.
- Take an in-person skills class. Local bicycle advocacy groups often run them, and an instructor can watch you approach an intersection and coach your position.
- Choose a route with fewer conflict points. A route with fewer busy turns and driveways reduces how often the situation arises.
- Use the "not yet" option. If one particular intersection feels beyond your comfort, walking your bike across it is a reasonable choice.
If you are hit in a crash, have your injuries checked by a medical professional. For legal questions about your state's rules, a local attorney or your state's bicycle advocacy group can explain what applies where you live.
FAQ
What is a right hook in cycling?
A right hook is a collision in which a driver turns right across a bicyclist who is going straight, and the bicyclist hits the side of the turning car. The City of Menlo Park describes it as "a bicyclist collides into the side of a turning car."
How do I avoid a right hook?
The League of American Bicyclists says not to ride on the right of motorists and to avoid the right side of a right-turn lane if you are not turning. Menlo Park advises watching for the car's right-turn signal and avoiding its blind spot. Both describe positions that make you easier to see before the turn begins.
Do cars have to yield to cyclists when turning right?
In California, Vehicle Code 21717 requires a driver who must cross an adjacent bicycle lane to turn to drive into the bike lane before turning. Other states and cities differ. Even where the law is clear, a driver may not have seen you.
Are intersections where most bicycle deaths happen?
Not most. PBIC's 2019 to 2023 figures show 62.7% of bicyclist fatalities occurred at non-intersections. About a third, 33.5%, were at urban intersections, and 3.5% were at rural intersections. These figures cover fatalities only.
Should I pass a car on the right at an intersection?
The League advises against it, saying "Do not ride on the right; motorists are not looking for other vehicles there." Menlo Park advises that if a car is already in the bike lane ahead of you waiting to turn, you pass it on the left or wait for it to complete its turn.
