Parking on highways — District of Columbia Permit Test
Parking on highways on the District of Columbia permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
You must never park on the paved or traveled part of any highway unless your vehicle is disabled and cannot be moved; pull to the right as far as possible.
Cars at highway speed expect the lane ahead to be moving, and a parked car in it is a sudden wall.
You must never park on the paved or traveled part of any highway unless your vehicle is disabled and cannot be moved.
When you park on the shoulder or side of any highway from sunset to sunrise, or when light is insufficient to see people or objects 1000 feet away, you must turn on your hazard lights or parking lights.
In poor light a car on the shoulder looks like part of the dark roadside until someone drifts into it.
When you park a vehicle on the shoulder or side of any highway from sunset to sunrise or when light is insufficient to see people or objects 1000 feet away, you must turn on your hazard lights or parking lights (if the vehicle is so equipped).
On the test
When may you park on the traveled part of a highway?
When the vehicle is disabled. Cars at highway speed expect the lane ahead to be moving, and a parked car in it is a sudden wall. DC Driver Manual, p.76: “You must never park on the paved or traveled part of any highway unless your vehicle is disabled and cannot be moved.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
