It comes after a horror triple fatality on the Midland Highway near Ross in October when a solar panel fell from a caravan, causing a head-on crash.

Acting Inspector Justin Lawson said specific incidents helped to highlight police priorities.

"Whenever something like that happens, as awful as that circumstance was, we need to capitalise on the learnings from that and look to educate the public as best we can so we can avoid a repeat of it," he said.

"A particular focus as we approach the Easter break is vehicles that are towing boats, caravans and trailers. We have seen in the past there have been some defects across that sort of vehicle range.

"Probably there's a bit of a culture where people have towed vehicles for a lot of years, they might think that by not having their left indicator working that that's reasonable because the chance of them getting pulled up is limited.

"We're here to disprove them."

To launch Operation Crossroads, police set up a random drug and alcohol testing site on the Tasman Highway at Warrane where traffic safety inspectors also looked at passing vehicles for towing issues.

In the hours since starting, inspectors had already identified multiple issues.

Acting Inspector Lawson said the inspections were more about raising awareness than issuing fines.

"We're entering into an education process, we're not looking necessarily for issuing infringement notices as much as educating the public about safety," he said.

In the first week of Operation Crossroads over Christmas, Tasmania Police issued 751 infringement notices with 27 drink and drug driving charges and 554 drivers caught speeding. There was one fatal and six serious crashes.
