Oklahoma Weigh Stations & Ag Inspection

When Oklahoma makes you pull in

Oklahoma runs ports of entry and weigh stations under its Weigh Station Act of 2012 (Okla. Stat. tit. 47 § 1200). Commercial trucks report when signs or an officer direct, and any DPS, Corporation Commission, or sheriff's officer can send you to the scale (§ 14-111). Ports near the state lines on I-35, I-40 and I-44 pre-screen electronically. Skipping an open station is a misdemeanor, commonly up to $500. PrePass and Drivewyze both bypass here: green rolls, red pulls in.

Stations, bypass, and inspection

• Who must stop: All CMVs must stop
• Where the stations are: Oklahoma's ports of entry and fixed scales sit on the main interstates near the state lines (I-35, I-40, I-44) and screen commercial traffic electronically. Hours vary and weigh-in-motion pre-screens at highway speed. DPS and Corporation Commission officers, plus sheriffs and their deputies, can direct you in or onto portable scales anywhere (§ 14-111).
• Bypass: Both PrePass and Drivewyze operate in Oklahoma at ports of entry and fixed scales on I-35, I-40 and I-44, with new PrePass sites added recently. Green light bypasses an open station; red or no signal means enter.
• Ag / border inspection: No highway produce or agricultural inspection stations. Oklahoma's ports of entry and weigh stations check weight, credentials and safety only.
• Fine for passing an open station: The Weigh Station Act itself sets no flat failure-to-stop dollar figure; bypassing an open station is charged as a misdemeanor under Title 47, commonly cited up to $500 and/or jail, with the exact amount set by the court. Overweight loads carry their own separate penalties.
