Delaware Truck Speed Limit
No split in Delaware. Trucks run the posted limit, same as cars — 65 mph on the rural stretches of I-95, I-495 and SR 1, and 55 mph where I-95 tightens through Wilmington (21 Del. C. § 4169). The statute's default cap is 55 on divided highways; DelDOT posts the 65 zones. Don't crawl — § 4171 bars driving slow enough to block traffic.
