An HOV lane is a special lane used only for carpools, buses, motorcycles, or decaled low-emission vehicles. You may use a carpool/HOV lane or on-ramp if your vehicle carries the posted minimum number of people required for the carpool lane, or you drive a low-emission vehicle displaying a special DMV-issued decal. If you operate a low emission and/or hybrid vehicle, you may be exempt from all toll charges on high occupancy toll (HOT) lanes. Motorcycle riders may use designated carpool/HOV lanes, unless otherwise posted.
Does the word "decaled" here refer to having a logo on the wind shield?
And why the writer has put HOV ( high occupancy vehicle ) lane beside an on ramp?

Visual example of HOV On-Ramp
Hmmm... the google street view data is old, so you can't see exactly what I'm talking about. But the right-hand lane of that highway on-ramp (the two lanes with the arrows in the center of the image, going off to the right) is now an HOV on-ramp. During busy hours, it may only be used by vehicles that qualify to use carpool lanes or which are certified low-emission vehicles.
Visual example of low-emission vehicle sticker
The decals showing that this car is a low-emission vehicle are the yellow ones on the car's back right bumper.
Note that in English, most words can be "verbed" (turned into verbs) even if the resulting meaning doesn't show up in a dictionary. The classic example is the phrase "Verbing weirds language", which means "Using non-verb words as verbs [verbing] makes language weird [weirds language]". This is an extreme example, meant to be humorous; but the meaning of a word used in this way will usually be clear from context.
