Delaware Truck Following Distance
300 feet - and Delaware ties it to following ANY vehicle, not just another truck. In a truck or a combination, outside a business or residence district, leave at least 300 feet behind the vehicle ahead so a passing car can pull in (21 Del. C. 4123(b)). It drops in town and never stops you passing. Elsewhere the general reasonable-and-prudent rule governs (4123(a)). First offense $28.75 to $75; a repeat within two years runs $57.50 to $95.
