[R.O. 2007 §335.020]
Whenever any ordinance of the City designates and describes a through street it shall be the duty of the City Traffic Engineer to place and maintain a stop sign, or on the basis of an engineering and traffic investigation at any intersection a yield sign, on each and every street intersecting such through street unless traffic at any such intersection is controlled at all times by traffic control signals; provided, however, that at the intersection of two (2) such through streets or at the intersection of a through street and a heavy traffic street not so designated, stop signs shall be erected at the approaches of either of said streets as may be determined by the City Traffic Engineer upon the basis of an engineering and traffic study.
[R.O. 2007 §335.030; Ord. No. 3138, 8-4-1994]
The City Traffic Engineer is hereby authorized to determine and designate intersections where particular hazard exists upon other than through streets and to determine whether vehicles shall stop at one (1) or more entrances to any such intersection in which event he/she shall cause to be erected a stop sign at every such place where a stop is required, or whether vehicles shall yield the right-of-way to vehicles on a different street at such intersection as prescribed in Subsection (B) of Section 335.040, in which event he/she shall cause to be erected a yield sign at every place where obedience thereto is required.
Any need identified and proposed for the installation of stop signs and/or yield signs, including those presented by O'Fallon residents, will be evaluated by the City Traffic Engineer to determine if it meets specific criteria as provided in this Section of this Title.
[R.O. 2007 §335.040; Ord. No. 3138 §§4—5, 8-4-1994]
Upon evaluation by the City Traffic Engineer, one (1) of the following processes shall be followed for the installation of proposed stop signs:
If the need meets the specific criteria contained in the Manual on Uniform Traffic Control Devices as published by the United States Department of Transportation the City Traffic Engineer shall authorize the installation of stop signs as funding is available. The manual on Uniform Traffic Control Devices suggests that, if one (1) or more of the following criteria exist, a stop sign may be warranted:
Intersection of a less important road with a main road where application of the normal right-of-way rule is unduly hazardous.
Street entering a through highway or street.
Unsignalized intersection in a signalized area.
Other intersections where a combination of high speed, restricted view, and serious accident record indicates a need for control by the stop sign.
Stop signs should never be used on the through roadways of expressways.
If the need meets the following specific criteria, the City Traffic Engineer shall authorize the installation of multi-way stop signs as funding is available. Any of the following criteria may warrant the installation of a multi-way stop sign:
Where electric traffic signals are warranted and urgently needed, the multi-way stop sign is an interim measure that can be installed quickly to control traffic while arrangements are being made for the electric signal installation.
An accident problem, as indicated by three (3) or more reported accidents in a twelve (12) month period, of a type susceptible of correction by the installation of a multi-way stop sign.
Where the volume of traffic on the intersecting roads is approximately equal and the following minimum traffic volumes are recorded:
The total vehicular volume entering the intersection from all approaches must average at least five hundred (500) vehicles per hour for any eight (8) hours of an average day, and
The combined vehicular and pedestrian volume from the minor street or highway must average at least two hundred (200) units per hour for the same eight (8) hours, with an average delay to minor street vehicular traffic of at least thirty (30) seconds per vehicle during the maximum hour, but
When the eighty-five (85) percentile approach speed of the major traffic exceeds forty (40) miles per hour, the minimum vehicular volume criteria is seventy percent (70%) of the above requirements.
The City Traffic Engineer will use the following criteria to evaluate the need for installation of yield signs. If one (1) or more of the following conditions exist, the City Traffic Engineer may authorize the installation of yield signs:
At the entrance to an intersection where it is necessary to assign right-of-way and where the safe approach speed on the entrance exceed ten (10) miles per hour.
On the entrance ramp to an expressway where an acceleration lane is not provided.
At intersections on a divided highway where the median between the roadways is more than thirty (30) feet wide. At such intersections, a stop sign may be used as the entrance to the first roadway of the divided highway and a yield sign may be placed at the entrance to the second roadway.
Where there is a separate channelized right-turn lane, without an adequate acceleration lane.
At any intersection where a special problem exists and where an engineering study indicates the problem to be susceptible to correction by use of the yield sign.
The driver of a vehicle approaching a yield sign if required for safety to stop shall stop before entering the crosswalk on the near side of the intersection or, in the event there is no crosswalk, at a clearly marked stop line, but if none, then at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway.
Except when directed to proceed by a Police Officer or traffic control signal, every driver of a vehicle approaching a stop intersection indicated by a stop sign shall stop before entering the crosswalk on the near side of the intersection or, in the event there is no crosswalk, shall stop at a clearly marked stop line, but if none, then at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway before entering the intersection.
[R.O. 2007 §335.060]
Except when directed to proceed by a Police Officer or traffic control signal, every driver of a vehicle approaching a stop intersection indicated by a stop sign shall stop as required by Subsection (B) of Section 335.050, and after having stopped shall yield the right-of-way to any vehicle which has entered the intersection from another highway or which is approaching so closely on said highway as to constitute an immediate hazard during the time when such driver is moving across or within the intersection.
[R.O. 2007 §335.070]
The driver of a vehicle approaching a yield sign shall in obedience to such sign slow down to a speed reasonable for the existing conditions and shall yield the right-of-way to any vehicle in the intersection or approaching on another highway so closely as to constitute an immediate hazard during the time such driver is moving across or within the intersection; provided, however, that if such a driver is involved in a collision with a vehicle in the intersection, after driving past a yield sign without stopping, such collision shall be deemed prima facie evidence of his/her failure to yield right-of-way.
[R.O. 2007 §335.080]
The driver of a vehicle within a business or residence district emerging from an alley, driveway or building shall stop such vehicle immediately prior to driving onto a sidewalk or onto the sidewalk area extending across any alleyway or driveway, and shall yield the right-of-way to any pedestrian as may be necessary to avoid collision, and upon entering the roadway shall yield the right-of-way to all vehicles approaching on said roadway.
[R.O. 2007 §335.090]
No driver shall enter an intersection or a marked crosswalk unless there is sufficient space on the other side of the intersection or crosswalk to accommodate the vehicle he/she is operating without obstructing the passage of other vehicles or pedestrians, notwithstanding any traffic control signal indication to proceed.
When any person driving a vehicle approaches a railroad grade crossing, the driver of the vehicle shall operate the vehicle in a manner so he/she will be able to stop, and he/she shall stop the vehicle not less than fifteen (15) feet and not more than fifty (50) feet from the nearest rail of the railroad track and shall not proceed until he/she can safely do so if:
A clearly visible electric or mechanical signal device warns of the approach of a railroad train;
A crossing gate is lowered or when a human flagman gives or continues to give a signal or warning of the approach or passage of a railroad train;
An approaching railroad train is visible and is in hazardous proximity to such crossing; or
Any other traffic sign, device or any other act, rule, regulation or Statute requires a vehicle to stop at a railroad grade crossing.
No person shall drive any vehicle through, around or under any crossing gate or barrier at a railroad crossing when a train is approaching while such gate or barrier is closed or is being opened or closed.
No person shall drive a vehicle through a railroad crossing when there is not sufficient space to drive completely through the crossing.
No person shall drive a vehicle through a railroad crossing unless such vehicle has sufficient undercarriage clearance necessary to prevent the undercarriage of the vehicle from contacting the railroad crossing.
Every commercial motor vehicle as defined in Section 302.700, RSMo., shall, upon approaching a railroad grade crossing, be driven at a rate of speed which will permit said commercial motor vehicle to be stopped before reaching the nearest rail of such crossing and shall not be driven upon or over such crossing until due caution has been taken to ascertain that the course is clear. This Section does not apply to vehicles which are required to stop at railroad crossings pursuant to Section 304.030, RSMo.
