How Is Fault Proved When a Driver Turns Left in Front of a Motorcycle?
Cover image: AI-generated illustrative streetscape; this is not a specific intersection or a reconstruction of a crash.
A driver turning across a motorcycle’s path may say the rider was never visible. To assess that explanation, investigators need to place both vehicles in the moments before the turn. The signal, speed and route of travel matter. So does the rider’s opportunity to avoid the collision. A failure to yield may be part of the case, but responsibility cannot be settled from the driver’s explanation alone.
Several sources may help place the vehicles. Police scene records, the damage and the impact location provide one set of clues; original approach video may supply the timing. Compare those with witness positions and any available signal timing records. Check where each image was taken before treating it as the driver’s view. The driver was seated at road level, not at an overhead camera’s position, and the light at noon differs from the light at night. If the dispute calls for an expert, counsel can obtain measurements of the lanes, obstructions and turn paths.
Illustrative evidence guide based on the article; the icons do not reconstruct a particular collision.
If the defense says the motorcycle came out of nowhere or was speeding, look for the basis of that claim. A violent impact or a rider’s landing point is not, on its own, a reliable speed calculation. A reconstructionist may use measured positions, video frames and reaction-time analysis to test a range of speeds. The question is whether the crash would still have occurred under other assumptions supported by the evidence, including a slower or faster approach.
Preserve the camera file in its original form. When identifying witnesses, distinguish those who saw the vehicles approaching from people who only saw the aftermath. Ask a family member to record each witness’s location while it is fresh. That information can fill gaps in a police diagram and help test sightlines. Counsel can then ask the driver to describe the sequence: where the vehicle stopped or slowed, what was visible, what obstructed the view and what triggered braking.
Does the turning driver always lose? No automatic rule decides every fact pattern. Signals, rider conduct, visibility and physical evidence must be evaluated together.

For over a decade he has shown an unwavering commitment to clients who were seriously injured by major accidents and industrial catastrophes. During that time he has earned the reputation as one of America’s most aggressive trial lawyers by achieving noteworthy recoveries from judges and juries, as well as substantial settlements prior to trial, the majority of which contained negotiated confidentiality agreements at the request of the defense. When asked about these cases, Mr. Herbert has said that each case not only justified the recovery level, but that no one would trade places with any one of these victims in return for any amount of money, once they know the facts and severity of the injuries and tragedy involved. According to Mr. Herbert, “there can be no substitute for passion, preparation and persistence in the practice of law”. He is known not only for this tenacious preparation, but also for his imagination in the courtroom.

There he graduated in the top of his class and became an eternal Sooners Football fan.

After spending a year as the top earning litigation attorney at a firm that frequently tops verdict search as one with the highest number of trial wins in Texas, Aaron accepted a position as a the managing pre-litigation attorney at another Dallas personal injury firm.
