What gap does the Maine handbook advise looking for when merging with moving traffic?
Correct answer: A gap of about 4 seconds
Why
The handbook uses a gap of about four seconds as a merging guide so that you and the driver behind have room to establish safe spacing. Judge the actual speed, visibility and traffic; a time count does not give priority or guarantee that an occupied or shrinking gap is safe.
