Dooring and Blind Spot Crash Claims in Houston, TX Opened Doors and Unseen Riders

The door statute, in full

Transportation Code §545.418(a) provides that a person may not open the door of a motor vehicle on the side available to moving traffic unless the door may be opened in reasonable safety without interfering with the movement of other traffic. Subsection (b) adds that a person may not leave a door on the side of a vehicle available to moving traffic open for longer than is necessary to load or unload a passenger. The section states no penalty of its own. What it does is place the obligation on the person opening the door, framed in terms of reasonable safety and interference with traffic rather than in terms of whether an approaching rider could have avoided the door.

How rare the reported event is

TxDOT's 2024 contributing factor table records 170 Texas crashes statewide with the factor of a door opened into a traffic lane, of which one was fatal and three involved suspected serious injuries. That figure counts all vehicle types and all road users, comes from crash reports as processed on April 9, 2025, and is not a Houston number. The reason the count matters is procedural rather than statistical: a factor recorded 170 times across an entire state is one an adjuster may have no template for, which makes the rider's own documentation of the door position, the parked vehicle, and the lane width unusually important.

Blind-spot merges are a lane-movement question

When the failure is a merge rather than a door, the governing duty is in Transportation Code §545.060(a): an operator on a roadway divided into two or more clearly marked lanes shall drive as nearly as practical entirely within a single lane and may not move from the lane unless the movement can be made safely. Section 545.061 adds that a vehicle entering a lane of traffic from the right yields the right-of-way to a vehicle entering the same lane from the left. Neither statute contains an exception for a vehicle the driver did not see, which is why the phrase describing a rider as being in a blind spot is a description of the driver's conduct rather than a defense to it.

The rider's lane entitlement

Transportation Code §545.0605, added effective September 1, 2023, states that a motorcycle operator is entitled to full use of a lane and that two motorcycles may be operated side by side within a single lane. It also forbids operating between lanes of traffic moving in the same direction and passing a motor vehicle within the same lane. A rider positioned toward one side of a lane, for pavement condition or visibility, is still using the lane the statute grants. That distinction is worth stating precisely in any written account, because an insurer's summary may compress lane position into a claim that the rider was somewhere unexpected.

Houston streets where doors and traffic share space

The City of Houston High Injury Network maps 906 half-mile segments of local, major, and frontage roads where deaths and serious injuries concentrated from 2014 through 2018, using a threshold of at least 4.5 severe crashes per half-mile and excluding major highways. Washington accounts for 5 of those segments and Yale for 4, both running through areas where curbside parking, loading, and through traffic occupy the same narrow space. The designation covers all road users and decides nothing about an individual crash. It does explain why the parked vehicle's position relative to the curb, the marked lane, and any bike lane belongs in the photographs.

What to photograph and write down

Capture the opened door or the merging vehicle in place if the scene has not been cleared, then the contact points: a door edge, a mirror, a front quarter panel, the motorcycle's bar end, brake lever, tank, or footpeg. Record the parked vehicle's plate, the time, the lane widths, and whether a loading zone, bus stop, or bike lane was marked. Keep the crash report number and the responding agency. Nothing here decides responsibility, and none of it is legal advice; it is general information about Texas statutes and published crash data.
