Legal Question in Traffic Law in Missouri

Based upon the facts your described, you seem to have a viable case. Even if the light was red, the other driver cannot turn until traffic is clear. If they were in the intersection while the light was green, there might be a chance that the driver can argue that you were 50% at fault. But, since he was turning, and you were going straight, it is his burden to prove that defense. Even then, their case may be weak. Sometimes one may turn right on Red, if the lane is clear. There is no allowance for turning left, as it by nature puts one into several lanes of traffic.

Hopefully, you called the Police, and they took a report at the scene. The other driver likely got ticketed for driving without insurance, and possibly failure to yield. You, or your attorney need to keep up with what happens in the other driver's traffic ticket case. You might be able to have the judge in that case order restitution to you as a precedent to accepting a plea deal between that driver and the traffic Court prosecutor. Hopefully, you can convince the the Prosecutor to make that part of any deal.

You say that you think you only have liability insurance. Have you checked with your insurer to see if you have uninsured motorist coverage? You might.

I suggest that you consult directly with a civil practice attorney, regarding this case. Do so soon, as your options may be limited, if you wait.

Good luck
