Police cannot extend a traffic stop beyond the time needed to deal with the original reason for stopping you — like writing a ticket — just to conduct a drug dog sniff or other investigation without reasonable suspicion.
A police stop exceeding the time needed to handle the matter for which the stop was made violates the Fourth Amendment.
Your traffic stop cannot be unreasonably prolonged. If the officer has issued your ticket, they generally cannot make you wait for a drug dog without additional suspicion.
