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.

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. 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.
E. 
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.

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 340.160.

State Law Reference — This Section has additional penalties 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.
It shall be unlawful to operate or use a Jacobs engine brake or other exhaust or engine device without a muffler or with a malfunctional muffler, as braking power to slow down a vehicle's rate of speed in the City, except in emergencies. For the purpose of this Section, a "Jacobs engine brake" is a hydraulic-electric engine attachment that converts a diesel engine into an air compressor by changing engine exhaust valve operation. Notice of this Section shall be posted at prominent locations in the City, by an appropriate sign notifying motorists of the passage of this Section.
