When any roadway has been divided into lanes, a driver of a vehicle shall drive so as to be entirely within a single lane and shall not move from the lane in which he is driving until he has first ascertained if such movement can be made with safety.
On all roadways the driver of a vehicle shall drive in the lane nearest the right side of the roadway when said lane is available for travel except when overtaking another vehicle or when preparing for a left turn.
The driver of a vehicle shall not overtake and pass a vehicle proceeding in the same direction unless there is sufficient clear space ahead on the right side of the roadway to permit the overtaking to be completed without impeding the safe operation of any vehicle ahead.
The driver of a vehicle when about to be overtaken and passed by another vehicle approaching from the rear shall give way to the right in favor of the overtaking vehicle, on suitable and audible signal being given by the driver of the overtaking vehicle, and shall not increase the speed of his vehicle until completely passed by the overtaking vehicle.
No person shall drive in such a manner as to obstruct unnecessarily the normal movement of traffic upon any street or highway. Officers are hereby authorized to require any driver who fails to comply with this section to drive to the side of the roadway and wait until such traffic as has been delayed has passed.
The driver of a vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard to the speed of such vehicle and the traffic upon and condition of the street or highway.
On roadways less than 27 feet wide and upon which vehicular traffic is permitted to operate in both directions, the driver of any slow-moving vehicle when traveling outside of a business or residential district shall not follow another slow-moving vehicle within 200 feet, but this shall not be construed to prevent such slow-moving vehicle from overtaking and passing another slow-moving vehicle. This section shall not apply to funerals or other lawful processions.
The driver of any vehicle, before starting, stopping, turning from a direct line or backing, shall first see that such movement can be made in safety. If the operation of another vehicle should be affected by a stopping or turning movement, the driver of such vehicle shall be given a plainly visible signal.
On such roadways as are divided by a parkway, grass plot, reservation, viaduct, subway or by any structure or area, drivers shall keep to the right of such a division except when otherwise directed by an officer, signs, signals or markings.
No operator shall enter upon the road surface of any street or highway or section thereof when, by reasons of construction, surface treatment, maintenance or the like or because of some unprotected hazard, such road surface is closed to travel and one or more signs, lights or signals have been erected to indicate that all or part of the road surface of the street or highway is not to be used, or when so advised by an officer, watchman, member of a street or highway crew or employee of the town, either audibly or by signals.
The driver of a vehicle shall not drive upon any sidewalk except at a permanent or temporary driveway.
A funeral composed entirely or partly of a procession of vehicles shall be identified as such by means of black pennants bearing a purple cross attached to the first vehicle.
A. 
It shall be the duty of each driver in a funeral or other procession to keep as near to the right edge of the roadway as is feasible and to follow the vehicle ahead as closely as is practicable and safe.
B. 
At an intersection where a lawful stop sign exists, the driver of the first vehicle in a funeral or other procession shall be the only one required to stop before proceeding through the intersection.
No vehicle shall be driven or moved on any street or highway nor shall any owner of any vehicle knowingly permit such vehicle to be driven or moved on any street or highway unless such vehicle is so constructed or so loaded as to prevent its contents from spilling, dropping, sifting, leaking or otherwise escaping therefrom. Vehicles loaded with any material which may be blown about by the wind shall be suitably covered to prevent the contents from being blown upon the streets or highways.
[Added 5-24-1937]
A. 
Every driver of a vehicle or other conveyance approaching an intersection of ways at which there is facing him an official sign bearing the word "stop," authorized hereby and which has been specifically approved in writing by the Department of Public Works of the Commonwealth of Massachusetts and such approval being in effect, shall, before entering and proceeding through the intersection, bring such vehicle or other conveyance to a complete stop at such line as may be clearly marked, or, if there is no line so marked, at a place between the said sign and the nearer line of the street intersection. When, however, a line of two or more vehicles approaches any such sign, the drivers of the second and third vehicles in the line shall not be required to stop more than once at said designated line or place or in the immediate vicinity thereof. This rule shall not apply when the traffic is otherwise directed by an officer or by any lawful traffic-regulating sign, signal or device, to any throughway established by the town or to a funeral procession as provided in § 199-38 of this article.
B. 
In accordance with the foregoing, the erection and maintenance of official stop signs is hereby authorized to be located and placed as follows:
