700 Basic Standard of Care

A person must use reasonable care in driving a vehicle. Drivers must keep a lookout for pedestrians, obstacles, and other vehicles. They must also control the speed and movement of their vehicles. The failure to use reasonable care in driving a vehicle is negligence.

Directions for Use

This instruction states the common-law standard of reasonable care in driving. It applies to negligent conduct that is not covered by provisions of the Vehicle Code: “Aside from the mandate of the statute, the driver of a motor vehicle is bound to use reasonable care to anticipate the presence on the streets of other persons having equal rights with himself to be there.” (Zarzana v. Neve Drug Co. (1919) 180 Cal. 32, 37 [179 P. 203].)

The instructions in this series should be used in conjunction with instructions on the elements of negligence contained in the negligence series.

Sources and Authority

The common-law duty supplements statutory driving regulations: “[A driver is] under a duty, both by statute and common law, to operate his vehicle without negligence so as to abstain from injuring any other person or his property.” (Bewley v. Riggs (1968) 262 Cal.App.2d 188, 194 [68 Cal.Rptr. 520].)

The standard of care is that of a reasonably careful person under the circumstances: “[The driver] was required to act as a reasonably prudent person under the same or similar circumstances … .” (Watkins v. Ohman (1967) 251 Cal.App.2d 501, 502–503 [59 Cal.Rptr. 709].)

“ ‘The degree of care required in watching the movements of a particular machine depends upon the facts and circumstances existing at the time and place of the accident’ and a driver is required to use that degree of care, only, which would be required of a reasonably prudent driver under similar circumstances.” (Whitford v. Pacific Gas and Electric Co. (1955) 136 Cal.App.2d 697, 702 [289 P.2d 278], internal citations omitted.)

The common-law requirement goes to the issues of lookout and control. Regardless of whether a driver was complying with the speed limit, “[he was] still bound to anticipate that he might meet persons at any point of the street and in order to avoid a charge of negligence he was bound to use ordinary care and to keep an ordinarily careful lookout for such persons and keep his machine under such control as would enable him to avoid a collision.” (Boccalero v. Wadleigh (1931) 113 Cal.App. 376, 379, [298 P. 526], internal citation omitted.)

“The operator of a vehicle must keep a proper lookout for other vehicles or persons on the highway and must keep his car under such control as will enable him to avoid a collision; failure to keep such a lookout constitutes negligence.” (Downing v. Barrett Mobile Home Transport, Inc. (1974) 38 Cal.App.3d 519, 524 [113 Cal.Rptr. 277].)

On the lookout requirement, one court observed: “The driver of an automobile is bound to use reasonable care to anticipate the presence on the highway of others who have equal right to be there and the fact that his vision is temporarily interfered with, either by the glaring sun or headlights, does not relieve him from that duty.” (Hill v. Peres (1934) 136 Cal.App. 132, 137 [28 P.2d 946], internal citations omitted.)

On the control requirement, one court observed: “Cases in which the problem has been presented adhere to the view that a driver must at all times exercise ordinary care to avoid a collision including swerving or altering his course, in addition to applying his brakes, if that would be a reasonable means of avoiding the collision.” (Guyton v. City of Los Angeles (1959) 174 Cal.App.2d 354, 362 [344 P.2d 910].)

“The age of a minor who operates a motor vehicle will not excuse him from liability for driving it in a negligent manner, and he will be required to meet the standard established primarily for adults.” (Prichard v. Veterans Cab Co. (1965) 63 Cal.2d 727, 732 [47 Cal.Rptr. 904, 408 P.2d 360].)

Drivers with mental disabilities are required to exercise the ordinary care required of an adult without such disability. (Fox v. City and County of San Francisco (1975) 47 Cal.App.3d 164, 173 [120 Cal.Rptr. 779].)
