Usually when going eastbound on this stretch of Y.L> Blvd, after passing Rio Del Oro, a Motorcycle cop will be waiting in the bushes on the Median, which has a small paved place that looks like it is meant for this very reason as it isn’t wide enough for much else. The limit is 40, but it is very easy to be going faster since Del Oro is for residential and usually lets traffic right through.
The entire stretch of Y.L. Blvd. is crawling with officers from Imperial Hwy. to La Palma, so Make sure that you drive 40, or they’ll write you up.
