Texas Practice Speed Limits

A Texas school zone sign shows a reduced speed. When is that reduced limit in effect?

  1. A.
    Only during arrival and dismissal periods.
  2. B.
    All day when school is in session.
  3. C.
    From 7 a.m. to 4 p.m. on weekdays.
  4. D.
    Only while the zone is active: when the yellow beacon is flashing, or during the hours the sign posts. Correct
The Why

The answer is "Only while the zone is active: when the yellow beacon is flashing, or during the hours the sign posts."

A school zone limit applies only while the zone is active. The manual's sign entry gives the beacon version: the speed shown is in effect when the yellow light is flashing. The authority that set the zone may instead post the hours on the sign, which is why the sign itself is what you read. Outside the active window the road returns to its ordinary limit.

Why the others miss

The traps in the wrong answers

A. Only during arrival and dismissal periods.

This answer ties the reduction to bell times, which the manual does not do. Guessed the reduction covered only bus loading and dismissal, skipping the flashing-light rule the manual sets.

B. All day when school is in session.

This answer extends the reduction past the window the sign sets. Copied from residential streets near schools that keep a low limit posted around the clock.

C. From 7 a.m. to 4 p.m. on weekdays.

A fixed clock window no Texas rule sets statewide. Where hours appear at all they are the ones on that sign, not a standard pair of times.
