Final answer:
The correct action for an orange light is not provided, so the answer is 'C. not enough information'. Traffic signals do not typically include an orange light, and standard rules should be followed unless otherwise instructed by local authorities.
Step-by-step explanation:
If the light is green, then the correct action is to stop. If the light is yellow, one should continue at current speed. If the light is red, the instruction given is to accelerate by 10 mph. However, these instructions do not align with standard traffic signal operations and can cause confusion. In the case of an orange light, which is not commonly recognized in traffic signals, the answer would be 'C. not enough information' because there is no standard action associated with an orange light, and typically traffic signals do not include an orange light phase. It is important to note that drivers should always follow the rules and laws set forth by their local traffic authority, which typically instruct drivers to stop at red lights, slow down and prepare to stop at yellow lights, and go if safe at green lights. An orange light is not standard, and the question does not provide enough context to determine a safe and legal action. Furthermore, to answer questions about whether cars travel at the correct speed limit and the safety of crossing the road without a pedestrian crossing, it would require more context about local traffic laws and conditions.
