Maryland Weigh Stations & Ag Inspection

When Maryland makes you pull in

Maryland posts signs at every scale telling any rig over 10,000 lb GVW or GVWR to pull in, so combined weight over 10,000 lb means you enter (Md. Transp. 24-111). Blow past an open Maryland scale and the minimum ticket runs about $520 (MDOT), with weight convictions reaching $1,000 on a first offense. Fixed and virtual scales sit on I-95, I-70 at Myersville, I-81 near Hagerstown, and I-68. WIM cameras flag runners even when the booth looks quiet.

Stations, bypass, and inspection

• Who must stop: Over a weight threshold
• Where the stations are: Fixed and virtual scales sit on I-95 (northeast, near Perryville), I-70 at Myersville, I-81 near Hagerstown, I-68, and US-50, backed by WIM cameras. Hours vary behind lit signs. MSP and MDOT also run portable scales, and virtual sites flag runners around the clock.
• Bypass: PrePass and Drivewyze both operate in Maryland, including the I-95 corridor scales and a park-and-ride bypass site. Green means stay on the mainline. The virtual/WIM sites still read your plate, so a green light doesn't excuse an overweight axle.
• Ag / border inspection: No agricultural or border produce inspection stations.
• Fine for passing an open station: Up to $1,000 on a first offense, up to $2,000 on a second, and up to $3,000 on a third or later for ignoring a scale sign, an officer's direction, or a CVISN signal to stop and be weighed (Md. Transp. § 24-111(d), (f)). You also owe the actual cost of the weighing your refusal forced (§ 24-111(d)(4)). The minimum ticket in practice runs about $520 (MDOT motor carrier guidance), and any overweight conviction is charged on top.
