Question Analysis
This question tests recognition of a regulatory traffic sign that prohibits passing. In the Texas Driver Handbook, signs with a red circle and a slash over a symbol indicate that the action shown is not allowed. A 'Do Not Pass' sign (often shown as a black left-curving arrow with a red circle and slash, or the word 'PASS' with a red slash) means you must not overtake or pass another vehicle in that area. This restriction is typically placed where passing is dangerous due to limited sight distance, curves, hills, intersections, or narrow roads. The sign remains in effect until the next passing-permitted zone or another sign changes the rule.
Correct Answer Analysis
Correct Answer: Must not pass another vehicle.
The correct choice is 'Must not pass another vehicle.' A 'Do Not Pass' sign is a regulatory sign that legally prohibits passing. It is not merely a warning; violating it can result in a citation. The sign indicates that passing is unsafe or illegal at that location, so the driver must stay in their lane and not attempt to overtake any vehicle, regardless of how slow the vehicle ahead may be or how clear the road appears.
Wrong Options Analysis
Option: May pass a slow-moving vehicle if you can do so quickly.
This is incorrect because a 'Do Not Pass' sign prohibits passing all vehicles, including slow-moving ones. The speed or quickness of the pass does not override the legal restriction. Passing in a no-passing zone is dangerous and illegal even if you think you can complete it quickly.
Option: May pass if you know the road ahead.
This is incorrect because personal knowledge of the road does not exempt a driver from a regulatory sign. The sign is placed based on official engineering judgment about safe passing conditions. Even if you believe the road ahead is clear, the sign legally forbids passing, and you must obey it.
Option: May pass, but only at night.
This is incorrect because the 'Do Not Pass' restriction applies at all times, day or night. There is no nighttime exception. Passing at night in a no-passing zone is especially dangerous due to reduced visibility and is still illegal.
