Yielding to an ambulance: what the law requires and the $500 fine

It is the rule for what to do when an ambulance, fire engine or patrol car approaches with its siren on. It is not “move over if you can”: the law describes a specific manoeuvre — pull to the right, stop, and stay stopped until it passes — and since Act 133-2026 failing to do it costs five hundred dollars.

Every driver in Puerto Rico. The article speaks of the driver of every other vehicle on the immediate approach of an authorised emergency vehicle sounding alarm signals.

• That it be an authorised emergency vehicle and that it be sounding alarm signals. The article conditions the duty on those two things.Verified against the official source
• That the approach be immediate. The law uses that word: “on the immediate approach”.Verified against the official source

• None. This is not a procedure: it is a traffic duty and its fine.

1. 1

   Step 1: Pull to the right, as close as you can

   The text is specific: the driver must yield and immediately position themselves parallel to, and as close as possible to, the right-hand edge or kerb of the roadway of the intersections. It does not say slow down or change lanes: it says position parallel and close to the right.

2. 2

   Step 2: Stop, and stay stopped until it passes

   The second half of the duty is forgotten more often than the first: the driver must stop and remain in that position until the authorised emergency vehicle has passed. Pulling out behind the ambulance, or following it to use the gap it opened, is not what the article allows.

3. 3

   Step 3: Unless an officer orders otherwise

   The article closes that duty with an exception: except when otherwise ordered by a law enforcement officer. If an officer is directing traffic at the scene, what they tell you overrides the general rule.

4. 4

   Step 4: The fine is now $500

   Anyone violating this article’s provisions commits an administrative offence and is sanctioned with a five hundred dollar fine. That is the change Act 133-2026 brought: it was one hundred before. Being an administrative traffic offence, the general rules on payment, discount and prescription of administrative fines apply to it.

5. 5

   Step 5: The ambulance has a duty too

   The same article says it: it shall not be construed to relieve the driver of an authorised emergency vehicle from the duty to drive with due care for the safety of all persons using the public way. The siren does not erase that duty.

Not applicable: there is nothing to apply for. The fine is issued like any administrative traffic offence and paid through the ordinary channels.

• Only slowing down: the article requires positioning parallel and as close as possible to the right kerb, and stopping.
• Pulling out before it passes: the duty is to remain in that position until the emergency vehicle has passed.
• Following the ambulance through the gap it opened: that is not what the article allows.
• Believing it is still a hundred-dollar fine: Act 133-2026 raised it to five hundred.
• Thinking the siren gives the ambulance free passage with no more: the article itself keeps the emergency driver’s duty to drive with due care.
