State v. Morrill
Once the reason for the stop is resolved, holding the driver to wait for a K-9 without reasonable suspicion of drugs unlawfully prolongs the stop. Consent to search obtained during that detention is tainted, and the evidence will be suppressed unless the State proves the taint was purged or attenuated.

State v. Sousa
An anonymous tip of drunk or erratic driving can justify a stop without your seeing bad driving, but only in limited cases. Courts weigh: enough detail (make, model, plate, location, direction) to be sure it is the right vehicle; how quickly you found it; whether the caller was a contemporaneous eyewitness; and whether the tip describes an actual driving offense.

Harlan v. State
New Hampshire's implied-consent law contemplates testing without unreasonable delay. A driver who refused could not cure the refusal by offering to take the test an hour later, and there is no right to consult a lawyer before deciding whether to submit. The court left open a refusal retracted almost immediately.
