Question

1. driving too slowly is: against the law. a safe option for drivers who are not confident. the responsibility of tired drivers. recommended by most law officers. 49. this sign means: emergency vehicles ahead. uncontrolled intersection ahead. four - way stop ahead.

Explanation:

• For question 48: Driving too slowly can impede traffic flow and is often against traffic laws. Options like being a safe option for un - confident drivers (can cause more problems), being a responsibility of tired drivers (not a valid reason), and being recommended by law officers (false) are incorrect.
• For question 49: The sign with a traffic light symbol typically indicates a traffic - controlled area. An emergency vehicle sign would have a different symbol (e.g., ambulance/fire - truck icon). An uncontrolled intersection sign usually has a different design. A four - way stop is related to traffic control, and this sign is more likely to be indicating a traffic - controlled situation (even though the exact match for four - way stop might be a bit of a stretch compared to a general traffic - controlled area sign, but among the options, it is the most relevant).

Answer:

1. Against the law.
2. Four - way stop ahead.
