Does Delaware’s two-hour statutory limit for a specified investigative detention allow every ordinary traffic stop to last two hours without justification?

Correct answer: No. It cannot outlast its lawful purpose without further justification.

Why

Section 1902 permits specified questions only when the officer has reasonable grounds to suspect a crime; it addresses name, address, business abroad and destination. It permits further investigation when the stated identification or explanation conditions are not met, with a two-hour ceiling and release or arrest-and-charge at the end. Constitutional limits also apply: a traffic stop cannot be extended beyond the time reasonably needed for its lawful tasks without an independent legal basis. The ceiling does not authorize a routine two-hour stop.
