The minimum clearance distance for any overpass you may encounter on your route is ______ if your trailer is 13'6" tall.

• A. 13'8" - 13'10"
• B. 15'6" - 16'
• C. 16' - 16'3"
• D. 14' - 14'2"

Answer: (D)

The main idea is that you must know the vertical space under overpasses and ensure it exceeds your vehicle height by a safe margin. For a trailer that is 13'6" tall, you should plan for at least 14 feet of clearance to have a bit of room for sag, suspension, and measurement variations. Among the given options, the smallest clearance that comfortably exceeds 13'6" is 14' to 14'2". This provides a practical buffer (about 6 to 8 inches), which is why it’s considered the minimum you might encounter on a route. The other ranges either fall below your height or don’t represent the minimum safe margin you’d reasonably expect on a typical route.
