Whether you're operating a vehicle or a boat this Fourth of July weekend, police will be on the lookout to ensure it's done in a safe manner.

Carbon County District Attorney Jean Engler held a news conference with Pennsylvania State Police and Pennsylvania Fish and Boat waterway conservation officers Friday to remind residents of the dangers of impaired driving and boating."There's going to be stepped up enforcement both on the highways and the waterways," Engler said. "We have this before the Fourth of July just to remind people to be safe and not drink and drive, and not drink and boat."Traffic is expected to be up on roads across Pennsylvania.This year, AAA predicts there will be 44 million people traveling at least 50 miles from home,PennDOT reported there were about 300 alcohol-related crashes on Pennsylvania roads during the Fourth of July holiday last year (July 1-10, 2016).That was slightly down from 2015, which could be attributed to the increased DUI enforcement.The legal limit for DUI in Pennsylvania is 0.08 percent BAC. In the most severe cases, the penalty for a first time DUI can include up to a $5,000 fine and 12 month license suspension.Boaters can be arrested for boating under the influence if an officer determines they are incapable of operating their watercraft, regardless of their BAC.In a news release put out in preparation for the holiday, the Pennsylvania DUI Association pointed out officers will be using standard field sobriety testing and advance roadside impaired driving testing to detect drivers under the influence of alcohol or drugs.Engler said that there were 50,000 DUI cases in Pennsylvania alone in 2016.While most of those were alcohol-related, there is an increasing number of drugged driving cases.Prescription drugs from a doctor can have just as much of an effect on one's ability to drive as illegal ones."The number of drug DUIs has just increased so much in the last few years," she said. "That's the one area where I think the public needs a push, needs to be more educated about."Residents who do plan to drink over the holiday are reminded to plan ahead and pick a designated driver."Sometimes it's just easier to just not drink at all than to monitor yourself," Engler said.
