The old way is broken

Stop reacting. Start controlling.

For years, truck owners and fleet managers have been stuck in the same reactive cycle. A warning light comes on, the truck derates, and suddenly you're losing time, money, and control.

01 — The warning light

A fault code appears. The truck loses power. Your driver is stranded on the side of the road trying to figure out what happens next.

02 — The scramble

Now you're calling shops, checking tow options, and guessing whether the truck can safely keep moving or needs immediate attention.

03 — The downtime

Every hour the truck sits still costs money. Missed loads, delayed deliveries, and expensive diagnostics start piling up fast.

With OTR — you take control

Dealer-level diagnostics, live fault data, remote commands, and real-time visibility, so small problems never become major downtime.

Saved me from a $1,200 shop visit. Forced a regen from my phone in 20 minutes and got back on the road. Pays for itself in one use.

We run 23 trucks. Before OTR Remote, a derate meant pulling the truck. Now I reset it from my desk and keep the load moving.

I knew about a DPF issue on truck 14 before my driver even noticed. That's the difference. You're ahead of the problem instead of behind it.
