Before answering this question, want a specification to was namely in our country highway code above all, if solid line is same,be the wall does not get line ball only, no matter be " odd Huang Shi, double Huang Shi, Bai Shi " if solid line is equal at the wall, uniform do not allow line ball! Differentia depends on pressing " white solid line " can fine 100 yuan (local not couplet net area or likelihood punish 200 yuan) , and overwhelm " yellow solid line " no matter sheet or double meeting are punished 200 yuan, buckle 3 minutes! And same is to want only it is dotted line, no matter yellow, white, odd, double all but line ball!
Say the distinction of single yellow solid line, double yellow solid line is in now, actually very simple, on the road that odd, double Huang Xian just uses at different width (Huang Xian is divisional right to driveway, the picture is in driveway center! And white line picture is in go up to driveway together! Do this understand? ) !
Double yellow solid line: Double yellow solid line is to be used differentiate " go up and down " direction has two each or two above motor vehicle, and the road that did not install central space belt. Spoken parts in an opera is a driveway two-way be equal to 4 driveway to be used greatly " double yellow solid line " ! 
Single yellow solid line: The line uses simple yellow fact to differentiate namely the road that only way has a roadway only or driveway of a motor-driven and motor vehicle of a blame. Spoken parts in an opera is a driveway two-way small be equal to two driveway use " single yellow solid line " ! 
This lists respecting understood, odd, double yellow solid line still has substaintial distinction, use divisional size namely actually, driveway is used more " double yellow " , driveway is used less " sheet is yellow " !
Appear when double Huang Xian " double empty " when, the car that that shows to fluctuation drive a vehicle all can jump over line travel! And double Huang Xian appeared " single dotted line " when, single dotted line is in wh which direction, the car of wh which direction can jump over line travel, and the car of solid line a side does not allow to exceed a line! 
As to " single yellow solid line " have a kind of case only, when occurrence sheet dotted line, also be " go up and down " car all can undertake passing through! 
Altogether, odd, double yellow solid line (want only actually it is solid line cannot be pressed) action is same really, do not allow line ball, but the applied domain that differentia consists odd, double yellow solid line is different, double yellow solid line is used in two-way the big wide driveway of 4 driveway and above, and what single yellow solid line uses in two-way double driveway commonly is narrow on the driveway!
