This is basically the exact same question as this question, but for Illinois, USA.
I witnessed a car waiting to turn right at a red light and then began to turn during a break in traffic and was almost struck by someone making a u-turn. The u-turner hit the brakes, honked, and gestured as if he had the right of way. The right-turner looked shocked as if he had the right of way.
I'm not sure if these facts are relevant, but I'll include them just in case:
- If there had been an accident, the u-turner would have struck the left side near the back end of the right-turner's vehicle, but fortunately stopped in time. (The right-turner got there first.)
- The u-turner was on a 4 lane road (2 lanes per direction) and turned into the right lane which was the same lane the right-turner turned into. However, I doubt the u-turner's vehicle could have turned tight enough to end up in the left lane, even if it was attempted.
Is the right of way defined for this scenario in Illinois?
Edit: after a little digging, this is the closest rule I can find:
Sec. 11-802. Limitations on U turns. (a) The driver of any vehicle shall not turn such vehicle so as to proceed in the opposite direction unless such movement can be made in safety and without interfering with other traffic.
If "other traffic" includes cars turning right, then I would interpret that as the right-turner having the right of way.
But that may conflict with this rule:
... vehicular traffic facing any steady red signal may cautiously enter the intersection to turn right...
...After stopping, the driver shall yield the right of way to any vehicle in the intersection or approaching on another roadway so closely as to constitute an immediate hazard during the time such driver is moving across or within the intersection or junction or roadways. Such driver shall yield the right of way to pedestrians within the intersection or an adjacent crosswalk.
This rule seems to suggest the u-turner would have the right of way. I think the problem is that the right-turner would expect the u-turner to be turning left instead of making a u-turn and therefore would not realize there is an "immediate hazard".
