Question 13

To solve this, we analyze each option:

• Option a: Solid yellow lines are for separating opposite - direction traffic, not for alerting lane departure.
• Option b: Rumble strips are designed to make a rumbling sound and vibration when a vehicle drives over them, which alerts drivers if they are leaving their lane.
• Option c: White dotted lines are for lane - changing or marking lanes in the same direction, not for lane - departure alert.
• Option d: Soft shoulders are the unpaved areas beside the road, not for alerting lane departure.

We analyze the options based on the definition:

• Option a: Focus time is a general term and not specific to regaining focus after glare.
• Option b: Scanning time is about the time to scan the road, not related to glare recovery.
• Option c: Glare recovery time is defined as the time it takes for a person's eyes to regain focus after seeing glare.

Answer:

b) Rumble strips
