A driver who did not enter the business can still face robbery liability if the evidence proves that the driver knowingly intended to help the robbery and actually assisted it at the required time. Learning about a theft only after property is picked up does not automatically end the inquiry: for robbery, the relevant carrying-away period can continue until the perpetrator reaches a place of temporary safety. But a ride, friendship, or presence alone does not establish aiding and abetting.
For liability as an aider of a completed robbery, the prosecution must prove that a perpetrator committed robbery. California’s general aiding instruction also requires proof that the person knew the perpetrator intended to commit the crime, intended to aid and encourage it before or during its commission, and in fact aided, promoted, encouraged, or instigated it. (Judicial Council of California Criminal Jury Instructions, CALCRIM 401) CALCRIM 1603 applies that framework to robbery: the intent to aid must form before or while the perpetrator is carrying the property away to a place of temporary safety. Under that instruction, temporary safety requires escape from the scene, no continuing pursuit, and unchallenged possession of the property. The driver need not personally use force if the elements of aiding the robbery are proved.
Put knowledge, intent, and assistance on a timeline
The key questions are when the driver learned what was happening, what the driver intended, and what assistance occurred before the carrying-away period ended.
| Timeline point | Facts counsel may examine |
|---|---|
| Before the incident | Messages, calls, route planning, agreement to wait, or other evidence of advance knowledge |
| During the taking | What the driver could see or hear, communications, and whether the driver knew property was being taken by force or fear |
| After property was taken | Whether the driver learned of the robbery, changed the route, helped avoid pursuit, or took another intentional step to aid escape |
| Temporary safety | Whether the perpetrator reached a place where the carrying away had ended under the instruction, considering pursuit and continued possession |
An innocent ride before the driver knows of a robbery differs from knowingly changing course to help the perpetrator escape while the property is still being carried away. The driver’s location, visibility, communications, timing, and conduct all may matter. Waiting nearby or driving away can be relevant evidence, but neither fact alone resolves knowledge, intent, or actual aid.
The rule for the driver differs from the rule for the taker
The direct taker’s liability can turn on whether force or fear was used to take or retain property and when the intent to take formed. A late-joining driver presents a different question: whether that person knowingly and intentionally assisted the robbery before the carrying-away phase reached temporary safety. These are separate analyses, even when they rely on the same video, calls, or pursuit evidence. (CALCRIM 1600 and 1603)
If the case also alleges a death or assistance only after the robbery was completed, counsel must assess the separate homicide or accessory rules. The robbery-aiding test alone does not decide those allegations.
For a case-specific assessment, counsel can review the timeline alongside complete recordings, call and message records, route data, witness accounts, and charging documents. Contact the Law Offices of David S. Chesley at (800) 755-5174 to discuss a California robbery charge.
