Practice question

What does the "basic speed law" in Texas dictate?

  1. Drivers must drive according to the posted speed limit only
  2. Drivers must adjust speed based on road conditions
  3. Drivers are allowed to exceed speed limits during emergencies
  4. Drivers must always drive under the speed limit

Answer: B — Drivers must adjust speed based on road conditions

The basic speed law in Texas requires drivers to adjust their speed based on road conditions. This means that even if the posted speed limit indicates a certain speed is acceptable, drivers must consider factors such as weather conditions, traffic, visibility, and road conditions when determining a safe speed. For example, during rain or fog, a driver may need to travel well below the posted limit to ensure safety. This law emphasizes the principle that safety should always take precedence over merely following speed limits, as conditions can change rapidly and may necessitate a slower speed for safe driving.
