In yesterday's column, we detailed the rights and the pitfalls for pedestrians in dealing with the D.C. police department's forthcoming crackdown on jaywalking pedestrians.

We noted that, in many situations, pedestrians may jaywalk legally.

Today we turn to the legalisms surrounding yellow (often called amber) and red signal lights, since the police also plan a crackdown against the epidemic of red-light runners. For starters, let it be said that there is very little -- if any -- leeway for one who runs a red signal to escape the full penalty of the law.

Here are the applicable provisions of the D.C. Municipal Regulations on the topic of signals, with Metro Scene supplying emphasis:

Paragraph 2103.4. "A steady yellow signal alone shall have the following meaning . . . that a related green signal is being terminated . . .and that vehicular traffic shall stop before entering the nearest crosswalk of the intersection, unless so close to the intersection that a stop cannot safely be made."

Paragraph 2103.7. "Vehicular traffic . . . shall stop before entering the crosswalk on the near side of the intersection or, if no crosswalk exists , then before entering the intersection."

Few ambiguities here. Yellow, in many instances, means stop; red, in all instances, means the same.
