Where are parking allowed on highways?

[LeBrady]

Here are the relevant introductions about where parking is allowed on highways: 1. Emergency lane: There will be signs indicating the emergency lane at intervals, and the emergency lane is usually marked with texts such as 'life passage' or 'rescue passage'. 2. Emergency parking area on highways: This kind of sign is not common on highways because it serves the same purpose as the emergency lane and requires corresponding space when set up. 3. Highway rest area: Highway rest areas generally only provide facilities such as public toilets, gas stations, benches, and a small number of parking spaces. 4. Highway parking lot: The difference between a highway parking lot and a rest area is that the parking lot is built in a service area outside the highway. 5. Highway service area sign: Highway service areas include the functions of both rest areas and parking lots, and also provide services such as dining, coffee (tea), hotels, and commodity sales.
