1. 
An operator or driver when stopping or when checking the speed of the operator's vehicle, if the movement of other vehicles may reasonably be affected by such checking of speed, shall extend such operator's arm at an angle below horizontal so that the same may be seen in the rear of the vehicle.
2. 
An operator or driver intending to turn the vehicle to the right shall extend such operator's arm at an angle above horizontal so that the same may be seen in front of and in the rear of the vehicle and shall slow down and approach the intersecting highway as near as practicable to the right side of the highway along which such operator is proceeding before turning.
3. 
An operator or driver intending to turn the vehicle to the left shall extend such operator's arm in a horizontal position so that the same may be seen in the rear of the vehicle and shall slow down and approach the intersecting highway so that the left side of the vehicle shall be as near as practicable to the centerline of the highway along which the operator is proceeding before turning.
4. 
The signals herein required shall be given either by means of the hand and arm or by a signal light or signal device in good mechanical condition of a type approved by the State Highway Patrol; however, when a vehicle is so constructed or loaded that a hand and arm signal would not be visible both to the front and rear of such vehicle then, such signals shall be given by such light or device.

2. 
"School bus" includes Head Start buses that meet the requirements set out in Section 304.050.1(2), RSMo.
B. 
Every bus used for the transportation of school children shall bear upon the front and rear thereon a plainly visible sign containing the words "School Bus" in letters not less than eight (8) inches in height. Each bus shall have lettered on the rear in plain and distinct type the following: "State Law: Stop While Bus is Loading and Unloading". Each school bus subject to the provisions of Sections 304.050 to 304.070, RSMo., shall be equipped with a mechanical and electrical signaling device approved by the State Board of Education, which will display a signal plainly visible from the front and rear and indicating intention to stop.
C. 
Every school bus operated to transport students in the public school system which has a gross vehicle weight rating of more than ten thousand (10,000) pounds, which has the engine mounted entirely in front of the windshield and the entrance door behind the front wheels, and which is used for the transportation of school children shall be equipped with a crossing control arm. The crossing control arm, when activated, shall extend a minimum of five (5) feet six (6) inches from the face of the front bumper. The crossing control arm shall be attached on the right side of the front bumper and shall be activated by the same controls which activate the mechanical and electrical signaling devices described in Subsection (B) of this Section. This Subsection may be cited as "Jessica's Law" in commemoration of Jessica Leicht and all other Missouri school children who have been injured or killed during the operation of a school bus.
D. 
Except as otherwise provided in this Section, the driver of a school bus in the process of loading or unloading students upon a street or highway shall activate the mechanical and electrical signaling devices, in the manner prescribed by the State Board of Education, to communicate to drivers of other vehicles that students are loading or unloading. A public school district has the authority pursuant to Section 304.050, RSMo., to adopt a policy which provides that the driver of a school bus in the process of loading or unloading students upon a divided highway of four (4) or more lanes may pull off of the main roadway and load or unload students without activating the mechanical and electrical signaling devices in a manner which gives the signal for other drivers to stop and may use the amber signaling devices to alert motorists that the school bus is slowing to a stop; provided that the passengers are not required to cross any traffic lanes and also provided that the emergency flashing signal lights are activated in a manner which indicates that drivers should proceed with caution and, in such case, the driver of a vehicle may proceed past the school bus with due caution.
E. 
No driver of a school bus shall take on or discharge passengers at any location upon a highway consisting of four (4) or more lanes of traffic, whether or not divided by a median or barrier, in such manner as to require the passengers to cross more than two (2) lanes of traffic; nor shall any passengers be taken on or discharged while the vehicle is upon the road or highway proper unless the vehicle so stopped is plainly visible for at least five hundred (500) feet in each direction to drivers of other vehicles in the case of a highway with no shoulder and a speed limit greater than sixty (60) miles per hour and at least three hundred (300) feet in each direction to drivers of other vehicles upon other highways, and on all highways, only for such time as is actually necessary to take on and discharge passengers.
F. 
The driver of a vehicle upon a highway with separate roadways need not stop upon meeting or overtaking a school bus which is on a different roadway, which is proceeding in the opposite direction on a highway containing four (4) or more lanes of traffic, or which is stopped in a loading zone constituting a part of, or adjacent to, a limited or controlled access highway at a point where pedestrians are not permitted to cross the roadway.
G. 
If any vehicle is witnessed by a peace officer or the driver of a school bus to have violated the provisions of this Section and the identity of the operator is not otherwise apparent, it shall be a rebuttable presumption that the person in whose name such vehicle is registered committed the violation. In the event that charges are filed against multiple owners of a motor vehicle, only one (1) of the owners may be convicted and court costs may be assessed against only one (1) of the owners. If the vehicle which is involved in the violation is registered in the name of a rental or leasing company and the vehicle is rented or leased to another person at the time of the violation, the rental or leasing company may rebut the presumption by providing the peace officer or prosecuting authority with a copy of the rental or lease agreement in effect at the time of the violation. No prosecuting authority may bring any legal proceedings against a rental or leasing company under this Section unless prior written notice of the violation has been given to that rental or leasing company by registered mail at the address appearing on the registration and the rental or leasing company has failed to provide the rental or lease agreement copy within fifteen (15) days of receipt of such notice.
A. 
The driver of a vehicle approaching an intersection shall yield the right-of-way to a vehicle which has entered the intersection from a different highway, provided however, there is no form of traffic control at such intersection.
B. 
When two (2) vehicles enter an intersection from different highways at approximately the same time, the driver of the vehicle on the left shall yield the right-of-way to the driver of the vehicle on the right. This Subsection shall not apply to vehicles approaching each other from opposite directions when the driver of one (1) of such vehicles is attempting to or is making a left turn.
C. 
The driver of a vehicle within an intersection intending to turn to the left shall yield the right-of-way to any vehicle approaching from the opposite direction which is within the intersection or so close thereto as to constitute an immediate hazard.
D. 
The driver of a vehicle intending to make a left turn into an alley, private road or driveway shall yield the right-of-way to any vehicle approaching from the opposite direction when the making of such left turn would create a traffic hazard.
E. 
The City may, on any section of road where construction or major maintenance operations are being effected, fix a speed limit in such areas by posting of appropriate signs, and the operation of a motor vehicle in excess of such speed limit in the area so posted shall be deemed prima facie evidence of careless and imprudent driving and a violation of Section 340.150.
[1]
Note — This Section has additional penalties to the general penalty based on certain circumstances, §304.351, RSMo.
The driver of a vehicle shall not follow another vehicle more closely than is reasonably safe and prudent, having due regard for the speed of such vehicle and the traffic upon and the condition of the roadway. Vehicles being driven upon any roadway outside of a business or residence district in a caravan or motorcade, whether or not towing other vehicles, shall be so operated, except in a funeral procession or in a duly authorized parade, so as to allow sufficient space between each such vehicle or combination of vehicles as to enable any other vehicle to overtake or pass such vehicles in safety. This Section shall in no manner affect Section 304.044, RSMo., relating to distance between trucks traveling on the highway.
A.
