The Best Trucking GPS
A car GPS will happily send an 80,000-pound truck under a 12-foot bridge. A trucking GPS will not. These units route around low clearances, weight limits and truck-restricted roads, and add truck parking, weigh stations and fuel prices. Here are the ones worth the money.

Best Overall
Garmin dēzl OTR620 (6")
The 6-inch dēzl OTR620 hits the sweet spot: custom truck routing, satellite imagery, community-shared loading docks and truck-parking availability in a size that does not swallow your dash. For most owner-operators this is the one to buy.

Best Mid-Size
Garmin dēzl OTR720 (7")
Same trucking smarts as the OTR620 with a larger 7-inch screen. A good middle ground if the 6-inch feels tight but the 10-inch feels like overkill.

Best Big Screen
Garmin dēzl OTR1010 (10")
A 10-inch display that is genuinely easy to read at a glance, with a directory of truck and trailer services and high-res satellite imagery. Best for drivers who want the biggest, clearest screen and have the dash room for it.

Best Non-Garmin
Rand McNally OverDryve 7 Pro
The main alternative to Garmin, with a 7-inch display, Bluetooth, SiriusXM and free lifetime maps. Worth a look if you prefer Rand McNally routing or want built-in radio.

| Feature | Why it matters |
|---|---|
| Truck-specific routing | The whole point. It routes by your height, weight and length to keep you off restricted roads and low bridges. |
| Screen size | Bigger is easier to glance at, but eats dash space. Six inches is the sweet spot; go 8 or 10 inches if your eyes prefer it. |
| Live traffic and parking | Truck parking availability and traffic rerouting save real time and stress at the end of a long day. |
| Free lifetime map updates | Roads and restrictions change. Make sure map updates are included so the routing stays accurate. |
Frequently asked
Do I really need a trucking GPS instead of my phone?
Yes, if you drive a commercial truck. Phone and car navigation apps route by car and will send you down truck-restricted roads and under low bridges. A trucking GPS routes by your height, weight and length, which is what keeps you legal and out of trouble.
What size trucking GPS is best?
A 6-inch unit like the Garmin dēzl OTR620 is the most popular size, big enough to read and small enough to fit the dash. Go to 7, 8 or 10 inches if you want a larger screen and have the room.
Are map updates free?
On the Garmin dēzl line and the Rand McNally units featured here, map updates are included. Always confirm the current terms on the listing, since programs change.
