Halloween to New Year's: What Pennsylvania Drivers Need to Know About Holiday DUI Enforcement

From Halloween through New Year's Day, Pennsylvania police run some of their most visible DUI enforcement of the year. This year Halloween falls on a Saturday, which means parties, bar crawls and trick-or-treat traffic all land on the same night, and that night begins a stretch of heavy enforcement that runs into January.

Pennsylvania State Police are already running a Halloween impaired-driving campaign that continues through November 1. After that, PennDOT and its safety partners typically launch Operation Safe Holiday, which runs through January 1 and focuses on impaired driving and seat-belt violations. Over just the five days of Thanksgiving 2025, State Police reported 458 DUI arrests, and those figures cover only crashes and arrests handled by PSP, not local departments.

Here is what drivers in Montgomery County and across Southeastern Pennsylvania should know before heading out this season.

The nights police focus on

Expect sobriety checkpoints, roving patrols and saturation patrols on and around these dates. Checkpoints are legal in Pennsylvania when police follow established guidelines, such as choosing locations based on data, stopping vehicles under a neutral pattern and giving advance public notice.

What Pennsylvania DUI penalties look like

Pennsylvania DUI law (75 Pa.C.S. § 3802) sorts most cases into three tiers based on blood alcohol concentration (BAC). Here is a simplified look at a first offense:

Every tier also requires an alcohol safety program and an evaluation for drug and alcohol treatment. Penalties climb steeply for a second or third offense, for accidents involving injury and for drivers with a minor in the vehicle.

If you are stopped

• Stay calm and be polite. Pull over safely, keep your hands visible and give the officer your license, registration and proof of insurance.
• You do not have to answer questions about your evening. You can politely decline to say where you were or how much you had to drink.
• Roadside field sobriety tests are voluntary. Walk-and-turn and one-leg-stand tests are not required by law, and declining them is not the same as refusing a chemical test.
• Take the chemical test seriously. Under Pennsylvania's implied consent law (75 Pa.C.S. § 1547), refusing a breath or blood test after a DUI arrest generally triggers a 12-month license suspension through PennDOT, separate from the criminal case. That suspension can be longer if you have prior refusals or DUIs.
• Write things down. As soon as you can, note the time, location, what the officer said and whether you were read your warnings.

A first DUI is not the end of the road

Many first-time offenders qualify for Accelerated Rehabilitative Disposition (ARD), a diversion program that can lead to dismissal of the charge and expungement of the record after successful completion. Eligibility depends on the county, the facts of the stop, your BAC and your history. An experienced lawyer can also challenge the stop, the checkpoint's compliance with the law, the testing procedure and the chain of custody of a blood sample.

License suspensions and refusal notices come with short deadlines. PennDOT refusal suspensions can be appealed, but only within 30 days of the notice's mailing date, so do not wait.

The best defense is a plan

1. Decide how you are getting home before the first drink.
2. Use a designated driver, a rideshare or public transit.
3. If you are hosting, offer non-alcoholic options and help guests arrange a safe ride home.
4. Remember that "the morning after" can still put you over the limit.
