It means to park, go straight or you can turn left or right.
Stop and think about how helpful a sign that says parking < ^ > is. (not)
We paid for the sign. Paid to install it. Paid a lawyer and a civil engineer to legally describe the sign's location too.
I really want to tear the damned thing down.
I want to know who thought we needed a sign to show people they can park anywhere but here and behind them.

It's also true that if you follow the signs, you end up at a garage that you pay the city to park in. Despite the fact that free parking is everywhere downtown.
