Nothing in the law requires that it be marked up in ANY fashion. You can be charged with Fail to Yield the ROW to an Emergency Vehicle if you fail to stop for an unmarked police vehicle.Texas Tranportation Code
§ 541.201. VEHICLES. In this subtitle:
(1) "Authorized emergency vehicle" means:
(A) a fire department or police vehicle;
§ 545.156. VEHICLE APPROACHED BY AUTHORIZED EMERGENCY
VEHICLE. (a) On the immediate approach of an authorized emergency
vehicle using audible and visual signals that meet the requirements
of Sections 547.305 and 547.702, or of a police vehicle lawfully
using only an audible signal, an operator, unless otherwise
directed by a police officer, shall:
(1) yield the right-of-way;
(2) immediately drive to a position parallel to and as
close as possible to the right-hand edge or curb of the roadway
clear of any intersection; and
(3) stop and remain standing until the authorized
emergency vehicle has passed.
Most officers will take into consideration if it was reasonable for you to be suspicious, and if you don't just attempt to ignore them.
