    Understanding DUI Checkpoints in Pennsylvania: What You Need to Know
    Driving under the influence (DUI) checkpoints are a common law enforcement tool used to catch impaired drivers before they can cause harm. However, many drivers in Pennsylvania may not fully understand their rights and responsibilities when encountering these checkpoints. If you or someone you know is facing DUI charges from a checkpoint stop, it’s crucial to know the law and how to protect yourself.
    Will a speeding ticket in Pennsylvania affect my automobile insurance?
    Receiving a speeding ticket in Pennsylvania can indeed impact your automobile insurance premiums. Insurance companies view speeding violations as indicators of increased risk, which often leads to higher rates. On average, Pennsylvanians may see their insurance premiums rise by approximately 19% following a speeding ticket. However, this percentage can vary based on factors such as the severity of the offense, your previous driving record, and the specific policies of your insurance provider.​
    What Police Can't Make You Answer in a Traffic Stop in Pennsylvania
    If you're pulled over by the police in Pennsylvania, it's important to know your rights. Many drivers feel pressure to answer every question or comply with every request, but the Constitution protects you from overreach. Here's what you are and aren't required to answer during a traffic stop in the Keystone State.
