When planning hazmat transport on an unfamiliar route, when should you check the route and permits?

• A. Before starting the trip
• B. After loading
• C. Midway through
• D. After arrival

Answer: (A)

Before starting a hazmat shipment on an unfamiliar route, you must verify the route and permits. Checking these before you depart ensures you know which roads allow hazmat traffic, what state or local permits may be required, and that those permits are valid for your vehicle and cargo. Hazmat routing can involve restrictions like tunnel or bridge bans, time-of-day limits, seasonal closures, and special permit or escort requirements. Confirming all of this upfront helps you choose a legal, safe path, secure any needed approvals, and have the correct documentation and placarding ready.

If you wait until after loading, you risk discovering a restricted route or expired permit, which can force dangerous, costly, or noncompliant changes. Checking midway through won’t protect you from new restrictions that arise after you’ve left, and checking after arrival is obviously too late.
