  1. Cross quickly
  2. Taxi onto the runway
  3. Stop or remain stopped ✔

Why: Red RELs mean high-speed traffic is on the runway or an aircraft is on final within the activation area. Stop and contact ATC if the lights conflict with your clearance.

Huh, didn't know that: REL fixtures form a red in-pavement line along the taxiway centerline toward the runway.

The red runway lights were outstanding in their field, mostly because everyone stopped.
