Most people picture a bicycle crash as a driver striking a rider from behind. In Cambridge the more common pattern involves a driver who never comes up behind you at all. The driver passes you and turns right across your front wheel, or approaches from the opposite direction and turns left through the space you are riding into. These are the right hook and the left cross, and they account for a large share of the intersection collisions that send cyclists in this city to the emergency room.
They also produce a predictable argument afterward. The driver says the cyclist came out of nowhere, or that nobody expects a bike on the right side of traffic. Massachusetts law answers both claims directly, and in the cyclist’s favor more often than insurers care to acknowledge.

A right hook happens when a driver overtakes a cyclist traveling in the same direction and then turns right at an intersection or driveway before the cyclist has cleared it. From inside the car it feels like an ordinary turn. From the bike it is a wall of sheet metal swinging into your path with no warning and nowhere to go.
Cambridge street design makes the collision common. Bike lanes run to the right of the general travel lane along Massachusetts Avenue, Cambridge Street, and Hampshire Street, three of the corridors where the city records the most bicycle crashes. That layout is safer on balance, but it places riders exactly where a turning driver is least inclined to look. Add a box truck with a long blind spot along its right flank and the geometry stops forgiving anyone. The Cycling Safety Ordinance commits the city to roughly 25 miles of separated lanes by late 2026, but the build-out does not help on the morning a driver cuts across your wheel. We looked at where these crashes cluster in our breakdown of Cambridge’s highest-risk streets for cyclists.
What Massachusetts Law Says About the Right Hook
The rule is specific and it is on the books. Under Massachusetts General Laws Chapter 90, Section 14, a driver who overtakes and passes a bicyclist proceeding in the same direction may not then make a right turn at an intersection or driveway unless the turn can be made at a safe distance from that cyclist, at a speed that is reasonable and proper.
That language disposes of the excuse drivers reach for first. The statute does not ask whether the driver signaled or whether the cyclist was visible in the mirror. It asks whether a driver who had just passed a cyclist then made the turn at a safe distance. If the answer is no, the driver violated the statute, and a statutory violation is evidence of negligence.
The same section carries related duties. A driver turning right must do so from the lane nearest the right-hand curb rather than swinging wide from a middle lane, and since the vulnerable road user law took effect on April 1, 2023, a driver passing a cyclist must leave at least four feet of clearance. A motorist who squeezes past a rider and then hooks right has usually broken more than one rule in the span of a block.

The Left Cross and the Duty to Yield
The left cross is the mirror image. A driver coming toward you turns left across your lane, into a side street or a parking lot, while you are riding straight through the intersection.
Chapter 90, Section 14 covers this as well. A driver turning left within an intersection, or into an alley, private road, or driveway, must yield the right of way to any vehicle approaching from the opposite direction that is within the intersection or close enough to constitute an immediate hazard. The statute then specifies that this includes a bicycle positioned to the right of the other approaching vehicles.
That clause carries weight in practice. The classic left cross unfolds when a line of oncoming cars sits stopped, a gap opens, and the turning driver takes it without checking whether a cyclist is coming through along the right side of that line. The driver afterward insists the bike was hidden. The Legislature contemplated that exact situation and placed the duty on the person turning.
Riding to the Right of Traffic Is Not a Defense
Adjusters frequently argue that a cyclist did something abnormal by moving up the right side of traffic, and that the crash therefore flows from the rider’s choice rather than the driver’s turn. Massachusetts forecloses that twice over. Chapter 85, Section 11B expressly permits a bicycle operator to keep to the right when passing a motor vehicle moving in the travel lane, so riding up the right side of slow traffic is lawful here.
Chapter 90, Section 14 then states plainly that it is not a defense for a motorist who causes a collision with a bicycle that the bicycle was to the right of vehicular traffic. That sentence exists because drivers kept making the argument anyway.
How Fault Gets Divided When the Driver Blames You
Massachusetts applies modified comparative negligence under Chapter 231, Section 85. If you carry some share of the blame your damages are reduced by that percentage, and if your share reaches 51 percent you recover nothing. In turning crashes the insurer’s standard play is to build that percentage upward, with claims about speed, lane position, lighting, or the absence of a helmet. Some bear on fault and some carry no weight at all, since Massachusetts requires a helmet only for riders 16 and under and provides that violating that rule is not evidence of contributory negligence. Sorting the real arguments from the noise is much of what a bicycle claim involves, and our longer discussion of fault when a car hits a cyclist walks through that split.

Call (617) 683-1983Who Pays the First Medical Bills
Massachusetts is a no-fault state for motor vehicle injuries, and the coverage follows the vehicle rather than only its driver. When a car strikes you while riding, the personal injury protection coverage on that vehicle’s policy generally pays up to $8,000 toward medical expenses and a portion of lost wages, regardless of fault. If you carry health insurance, PIP typically covers the first $2,000 of medical bills before your health plan takes over. The same framework applies whether you were on your own bicycle, a Bluebikes rental, or a conforming electric bike.
PIP is a floor, not a resolution. Serious injuries pass $8,000 quickly, and everything above that comes from the driver’s bodily injury liability coverage, which since July 1, 2025 starts at a $25,000 per person and $50,000 per accident minimum in Massachusetts. Damage to the bicycle sits outside PIP as a property claim, so you have to establish fault to be paid for the bike. If you are early on, our guide to being hit by a car while biking in Cambridge covers the opening steps.
What to Do After a Turning Crash
Turning cases are won and lost on details that disappear fast. Vehicle positions, signal use, and timing all get contested later, and the record you build in the first day or two usually decides how that argument goes.
- Call the police and make sure a report is written, even if you think you can ride away.
- Photograph the intersection, the lane markings, the driver’s final position, and your bike before anything moves.
- Ask nearby businesses about exterior cameras, since footage is often overwritten within days.
- Get medical attention the same day, because adrenaline masks injuries and a treatment gap is the first thing an adjuster will use against you.
- Keep the damaged helmet and bike as they are, and give no recorded statement to the driver’s insurer before speaking with a lawyer.
Watch the deadlines. Under Chapter 260, Section 2A, most Massachusetts personal injury lawsuits must be filed within three years of the crash. Claims involving a city or state agency, which can arise where roadway design contributed, run on far shorter notice periods measured in months.
