Traffic signs and pavement markings:
- Must always be obeyed. ✓
- Are merely suggestions.
- Must be followed only when there is other traffic.
- Must be followed only when a police officer is present.
Answer: A. Must always be obeyed.
Traffic signs and pavement markings must always be obeyed.
Why this is the answer
The handbook says pavement lines, symbols, and words are painted to direct drivers and control traffic flow, and it tells you to know their meanings and obey them. It also explains that traffic signs give rules, warnings, and directions, and that regulatory signs control traffic, set limits, or give commands. Nothing in those passages makes obedience depend on other cars or on a police officer being there.
Why the other answers are wrong
- B. Are merely suggestions. — They are not suggestions, because the handbook says to obey pavement markings and describes regulatory signs as setting limits and giving commands.
- C. Must be followed only when there is other traffic. — Other traffic does not change the rule, since the passages state that markings and signs are used to direct and control traffic without making obedience conditional on traffic being present.
- D. Must be followed only when a police officer is present. — A police officer's presence is not required, because the passages treat signs and pavement markings themselves as traffic controls that drivers must follow.
Remember it
Treat every sign and painted line as a rule, not a hint.
