Erie, Pa (WJET/WFXP) — Ahead of winter weather impacting the region this weekend, PennDOT has announced new vehicle and speed restrictions.

Tier 1 vehicle restrictions were in effect overnight, but have since been replaced by the more restrictive Tier 4 restrictions. This restriction change started at 5 a.m. and will last until further notice on the following roads:

• Interstate 90 from the Ohio state line to the New York state line.

• Interstate 86 from I-90 to the New York state line.

• Interstate 79 from Exit 147 (Route 19/Route 322/Route 6/Meadville) to the end of I-79 in Erie County.

Under Tier 4 restrictions, ALL commercial vehicles are banned from traveling along these roadways. This includes school buses, motor coaches, motorcycles, RVs/motorhomes, and passenger vehicle towing trailers.

Speed limits will be restricted to 45 mph on these roadways for all vehicles while the vehicle restrictions are in place.

PennDOT states these restrictions are in place to help ensure the interstates remain open during the most challenging conditions of the winter storm. These restrictions will be removed once PennDOT confirms conditions have improved.

What happens if you’re involved in a crash?

As bad winter weather can lead to accidents, drivers are asked to follow this advice from state police if they are involved in a crash:

• Move your vehicle as far as possible from the travel lanes if it’s able to be driven. Remaining in the lanes of travel when your vehicle can be driven is extremely dangerous.
• If your vehicle or another involved vehicle is not able to be driven due to damage, or if one of the involved parties is injured, PA law requires the crash be reported to police. Do this by dialing 911 right away.
• If your vehicle is disabled in the lane of travel or stuck in the travel lanes due to snow or ice, remain inside the vehicle with your seatbelt on and hazard lights activated. If it’s not safe to remain inside your vehicle, assess the situation and get yourself and passengers to a place of safety such as behind a barrier or guardrail. When exiting your vehicle, move as quickly as possible and DO NOT remain in the travel lanes or near your vehicle.
• When encountering a crash scene, the law requires you to move over if possible and always slow down. First responders will be active at the scene and focused on helping those involved in the crash and getting the road back open.

Laws to remember for winter weather driving

Pennsylvania law requires all drivers to remove accumulated ice or snow from their vehicle, including the hood, trunk, and roof within 24 hours after the storm has ended.

Drivers in violation can receive a fine of $50. They can also be cited up to $1,500 if snow or ice is dislodged and strikes another vehicle or pedestrian causing death or serious injury.
