On roads with lane signals, what does a yellow X mean? A. The lane is about to close or direction is changing. B. The lane is closed or is being used for oncoming traffic. C. You are driving in the right direction, but you should slow down. D. Yield to vehicles changing lanes in front of you.

A yellow X above a lane on the road generally means that the lane is about to close or change directions. This is a warning signal indicating to drivers that they should prepare to safely vacate the lane. It's important to look for a sign or signal that will show which direction to move or to find an alternative route if necessary. This may involve merging into another lane that will remain open for your direction of travel.

 A yellow X over a traffic lane typically means that the lane you are in is about to close or change directions. It is a warning signal indicating that you should prepare to vacate the lane safely. Drivers are expected to transition out of that lane as soon as it's safe to do so. So, the correct answer is A. The lane you're in is about to close or change directions.

On roads where the flow of traffic can be altered by lane signals, different symbols or lights indicate the status of the lane:

- A green arrow pointing downwards means the lane is open to traffic moving in the direction of the arrow. - A steady red X sign indicates that the lane is closed to traffic and you are not permitted to drive in it. - A flashing red X means the same as a steady red X, though it might be used in more urgent or temporary situations. - A steady yellow X or a flashing yellow X, as in this question, warns that a change is imminent; it might become a red X or the direction of travel in that lane may change. This is often utilized for reversible lanes, which can switch the direction of traffic flow during different times of the day to accommodate rush hour traffic. - A white, steady, one-way left diagonal arrow indicates that the lane is only to be used for left turns. - A white, steady, two-way left diagonal arrows indicate that the lane is a shared center lane for left turns from both directions.

Understanding these signals is crucial for safe driving and maintaining efficient traffic flow, as they allow lanes to be used flexibly and for different purposes at different times. It's also important for drivers to remember that traffic signs and signals may be subject to regional variations, so it's always a good idea to familiarize yourself with the specific road rules in your area or any area you plan to drive in.
