Final answer:
The statement that a line of sight search should extend at 12 seconds in front of the vehicle is True. This practice allows drivers to have sufficient time to react to possible hazards on the road.
Step-by-step explanation:
True or False: A line of sight search should extend at 12 seconds in front of the vehicle. The statement is True. It is recommended for drivers to maintain a visual lead time of about 12 to 15 seconds ahead of their vehicle. This allows for adequate time to react to potential hazards on the road. For example, if Bridget saw cars taking 3 seconds to travel between two poles that are 50 meters apart, she could estimate the cars' speed and determine if they are within a safe traveling speed given the conditions of that road. Similarly, Nelson, while observing traffic, can calculate average speeds and compare them with known limits such as the 140 km/hr speed recorded by the traffic officer.
