Are roadblocks constitutional?

Generally, roadblocks are constitutional if certain procedures are followed by law enforcement officers. Under State v. Kirk, the court held that temporary road block set up by exercise of absolute, unbridled discretion of officers in field is violative of State Constitutional provision against unreasonable seizure; however, if certain procedures set forth, ensuring supervisory control of checkpoints and warnings to motorists, are carefully followed, any constitutional objections will be overcome.
