DOT vs. Off-Highway... What's the Difference?

The off-highway Kalmar Ottawa T2 model specifically moves semi-trailers around warehouses, trucking terminals, ship ports, distribution centers, or any place involving a semi-trailer moving in an environment without accessing a public road. The off-highway Ottawa would not have the street legal features that a DOT (Department of Transportation) spotter would have, including speed.

The off-highway Ottawa T2 spotter has a top speed of 25 MPH and can be programmed to run at any speed under 25 MPH. The DOT Kalmar Ottawa T2 has legal access to public roadways.

DOT spotters are generally prohibited from running on interstate highway systems. If you take any trailers off-site to your local warehouse, the DOT Kalmar Ottawa spotter would fit this application. Street legal features of the new DOT Kalmar Ottawa T2 spotter will include a Tier 4 (T4F, or stage V) clean idle-compliant engine and a license plate with a VIN number and title.

DOT spotters must have an annual inspection by a licensed DOT inspector. That inspection must always be with the vehicle until that inspection expires. Depending on the year and the ABS braking system, the DOT spotter will have a speed of around 33 MPH or more.
