Police on Oahu are stepping up DUI enforcement before Labor Day weekend, bad news for anyone planning to drink and drive and good news for other drivers.

• A DUI checkpoint ran overnight along a Kapolei parkway, and several drivers were arrested on suspicion of driving impaired.
• The crackdown is part of a nationwide push to get impaired drivers off the road over the holiday.
• MADD Hawaii and Honolulu police are running the effort together.
• Drivers are being urged to line up a safe ride home before going out.

Outlook: Expect more checkpoints and stepped-up patrols across Oahu through the holiday weekend.
