Portage la Prairie firefighters were called out around 6 last night, to deal with a fire inside a trailer on the Trans Canada Highway.

It happened about 2 miles west of the Highway 13 junction, in an enclosed trailer belonging to a company that paints lines on streets and roads.

A fire official says a tire blew on the trailer, so they pulled over, and the trailer was unhitched.

The fire caused only minimal damage to the trailer's interior, and so far, it's unclear how it started.

There were no injuries, and no damage estimate's available.
