The stretch of Plano Parkway going from Midway out towards 121 as you’re heading towards Austin Ranch/Lewisville is heavily enforced by Carrollton PD. Be especially careful going down the steep hill in front of the new school. You’ll have to ride the brakes hard to avoid getting a ticket if they’re out that day. I’m all for enforcing school zone speed limits but this seems fishy to me. The school zone lights are flashing even though it’s outside the hours posted on the sign and also on weekends and during the holidays when school is not even in session. One person I know was ticketed at 9:10 for violating the school zone which expired at 9:00. The officer claimed the current time was earlier than 9:00 which was not true.
