(1) An operator or driver when stopping, or when checking the speed ofthe operator's vehicle, if the movement of other vehicles may reasonably beaffected by such checking of speed, shall extend such operator's arm at anangle below horizontal so that the same may be seen in the rear of thevehicle;
(2) An operator or driver intending to turn the operator's vehicle tothe right shall extend such operator's arm at an angle above horizontal sothat the same may be seen in front of and in the rear of the vehicle, andshall slow down and approach the intersecting highway as near as practicableto the right side of the highway along which such operator is proceedingbefore turning;
(3) An operator or driver intending to turn the operator's vehicle tothe left shall extend such operator's arm in a horizontal position so that thesame may be seen in the rear of the vehicle, and shall slow down and approachthe intersecting highway so that the left side of the vehicle shall be as nearas practicable to the center line of the highway along which the operator isproceeding before turning;

The provisions of this subdivision shall not applyto any trailer which does not interfere with a clear view of the hand signalsof the operator or of the signaling device upon the vehicle pulling suchtrailer; provided further that the provisions of this section as far asmechanical devices on vehicles so constructed that a hand and arm signal wouldnot be visible both to the front and rear of such vehicle as above providedshall only be applicable to new vehicles registered within this state afterthe first day of January, 1954.

(L. 1953 p. 587 § 304.020, A.L. 1996 H.B. 1047)(1954) Where plaintiff admittedly did not give hand signal of his intention to stop, and other evidence was to the effect that no electric stop signal was seen, question of contributory negligence in failing to give warning of stop held for jury even though car was equipped with adequate electrical signaling devices. White v. Rohrer (Mo.), 267 S.W.2d 31.
(1958) Under the circumstances of the case, whether defendant was guilty of negligence in failing to give signal of intention to turn right at driveway was question for jury. Ilgenfritz v. Quinn (Mo.), 318 S.W.2d 186.
(1959) Where driver gave timely and adequate signal of intention to stop by means of a stop light on left rear of vehicle operated off of the brake, he was not required to give hand signal. Pilkenton v. Fegley (Mo.), 321 S.W.2d 435.
(1961) Section 304.019 is not limited to cases where there is a sudden checking of speed but the degree of abruptness would have a decided bearing upon whether it would reasonably affect the movement of a following vehicle. Lafferty v. Wattle (A.), 349 S.W.2d 519.
(1964) A motorist who intends to turn left may not assume that other vehicles will not be on the highway in violation of rules of the road and must make proper observation to rear to see that another vehicle is not coming into such close proximity that a left turn cannot be made with reasonable safety and must give appropriate signal of intent to turn left. Reed v. Shelly (A.), 378 S.W.2d 291.
(2004) Signal requirement does not apply to vehicles moving from stopped position and entering traffic; probable cause did not therefore exist for police officer to stop vehicle after defendant pulled vehicle onto street from parked position without signaling. State v. Johnson, 148 S.W.3d 338 (Mo.App.W.D.).
