The California Air Resources Board has been out in full force for the past year making sure truck drivers are within regulation.

Today they targeted the Calexico border crossing.

Enforcement teams have been in the Imperial Valley but this is the first time the educational team has come out to make sure that truckers comply with the policy.

Truck driver Pedro Roman feeling good. He didn’t get a ticket.

"I’m lucky because they put a new filter in San Diego. Some kind of system to clean the air," truck driver Pedro Roman said.

Clean air is exactly the goal of the California Air Resources Board. This state has the worst air quality in the nation.

They’re helping the enforcement team check various trucks.

"Deisel trucks and the exhaust from diesel trucks contribute not only to smog but they also contribute to toxic air emissions. The diesel soot is toxic," Bruce Tuter of ARB said.

This is why they’re making sure truck drivers are informed on what they need to do to comply.

These regulations affect 200,000 businesses.

"Those that do comply are not only helping the folks in California providing a cleaner environment but they’re probably going to avoid getting a ticket when we’re out at events like this," Tuter said.

He says the main thing is that these trucks need to have a 2010 engine or newer and that a filter that traps the diesel soot is in place.

A majority own their trucks.

"They don’t have the resources to understand what they need to do so to get full compliance to get these emissions reduced, we’ve been out here with our enforcement staff to to try and make sure exactly what they need to do," Tuter said.

"It’s important because the world is contaminated. Everything is messed up you know," Roman said.

This is going to be an ongoing effort to make sure that our air quality stays safe.
