Route Planning Tips for Truck Drivers
Good route planning is the difference between an on-time delivery and a costly mistake. A wrong turn under a low bridge or onto a weight-restricted road can end your day — or your career. This guide covers the essential tools, strategies, and planning habits every truck driver needs, whether you are planning a flip-flop or a coast-to-coast run.

Truck GPS vs Car GPS: Why It Matters
The single biggest mistake new truck drivers make is using a car GPS for truck routing. Car GPS systems like Google Maps and Apple Maps do not account for bridge heights, weight limits, truck-prohibited roads, or commercial vehicle restrictions.
Trucker Path — The most popular trucking app with over 800,000 users. Offers truck-specific routing, truck stop reviews, fuel prices, parking availability, and weigh station status. Free tier with premium upgrade for advanced routing. Includes bridge heights and weight restrictions.
CoPilot Truck — Professional truck GPS with offline maps that work without cell service. Allows custom vehicle profiles for height, weight, length, and hazmat. Route comparison feature shows multiple options with time and distance. One of the most accurate systems for truck-specific routing.
Garmin dezl — Standalone GPS devices with large screens (7 to 8 inches) designed for commercial vehicles. No cell service required. Includes bridge database, truck-specific points of interest, and custom vehicle profiles. The dezl series is the gold standard for dedicated truck GPS hardware.
Never Trust a Single Source for Bridge Heights
Planning for Restrictions and Regulations
Beyond bridge heights, truck drivers face a web of routing restrictions that car drivers never encounter.
Weight-restricted roads and bridges — Many secondary roads and older bridges have posted weight limits below 80,000 pounds. County roads may limit trucks to 40,000 or even 20,000 pounds. Violating weight restrictions can result in fines and bridge damage liability.
Hazmat routing — Drivers hauling hazardous materials must follow designated hazmat routes. Many tunnels (like the Lincoln and Holland tunnels in New York) and some bridges prohibit hazmat vehicles entirely. Set your GPS to hazmat mode and check state-specific hazmat route maps before departure.
Truck-prohibited roads — Some parkways, residential streets, and scenic byways prohibit commercial vehicles regardless of weight. The Garden State Parkway in New Jersey and the Merritt Parkway in Connecticut are well-known examples. Fines for driving a CMV on a prohibited road can be severe.
Fuel and Rest Stop Planning
Running out of fuel or running out of legal driving hours without a safe place to park are avoidable problems that proper planning eliminates.
Fuel stop spacing — Plan fuel stops every 400 to 500 miles. Never let your tank drop below one-quarter full. Use fuel price comparison apps and your fuel card network to save $0.10 to $0.30 per gallon. A 200-gallon fill-up at $0.20 less per gallon saves $40 per stop.
Parking planning — Truck parking is scarce after 6 PM at most major truck stops. Plan your 10-hour break location by early afternoon. Apps like Trucker Path show real-time parking availability. Rest areas, Walmart lots (where permitted), and reserved parking programs are alternatives when truck stops are full.
HOS timing — Plan your Hours of Service around your route. If you have 6 hours of drive time remaining and your destination is 7 hours away, you need a stopping point with parking. Building HOS awareness into your route plan prevents forced stops on highway shoulders.
Seasonal Route Adjustments
Weather and seasonal conditions require route adjustments that go beyond checking the forecast.
Winter routes should avoid mountain passes when chains are required (unless you carry chains and know how to use them). Spring brings road construction season — plan for delays and detours on major interstates. Summer heat can cause tire blowouts, so plan routes with good shoulders and avoid running on underinflated tires. Fall brings harvest equipment on rural roads and earlier darkness.
Check state DOT websites and the 511 travel information system for real-time road conditions. Many states offer free apps and text alerts for commercial vehicle restrictions and weather-related closures. Planning around these conditions is not optional — it is a professional requirement.

Route Planning FAQ
Common questions about truck route planning and navigation
What is the best GPS app for truck drivers?
The best truck GPS apps in 2026 are Trucker Path, CoPilot Truck, and Garmin dezl. Trucker Path offers truck-specific routing with bridge heights, weight limits, and truck stop reviews. CoPilot Truck provides offline maps and customizable vehicle profiles. Garmin dezl devices are standalone GPS units with large screens designed for trucking. Never use a standard car GPS like Google Maps or Apple Maps for routing — they do not account for truck restrictions.
How do I check bridge height clearances for my truck route?
Bridge height clearances can be checked through truck GPS apps (Trucker Path, CoPilot), state DOT websites, and the National Bridge Inventory. Standard overhead clearance on interstate highways is 14 feet minimum, but many older bridges, underpasses, and overpasses on non-interstate roads are lower. Always know your loaded height before departing and add 6 inches of buffer for road surface variations and tire pressure changes.
Do hazmat loads require specific routes?
Yes, hazmat loads must follow designated hazmat routes in many cities and states. Federal regulations (49 CFR 397) require hazmat drivers to use routes that minimize risk to populated areas. Many tunnels, bridges, and urban corridors prohibit hazmat vehicles entirely. Your truck GPS should be set to hazmat routing mode, and you should verify restricted areas with local authorities before departure.
How far apart should I plan fuel stops?
Plan fuel stops every 400 to 500 miles or when your tank reaches one-quarter full, whichever comes first. Running low on fuel in remote areas or during bad weather is dangerous and stressful. Use fuel price apps like GasBuddy or the Trucker Path fuel feature to find the cheapest diesel along your route. Fuel network cards like EFS and Comcheck often offer discounted rates at specific truck stops.
