The sequence of traffic lights in Ireland is green, amber, red and green again. Red light: “stop” - do not go beyond the stop line at the light or, if there is no stop line, beyond the light. Green light: go on if the way is clear - take special care and give way to pedestrians who are crossing, if you turn left or right. Green arrow (also known as the filter light): you may move on in the direction of the arrow, assuming it is safe and the way is clear, even if a red light is also showing. Always look out for emergency vehicles that may be responding to an incident using blue lights and sirens. Amber light: do not go beyond the stop line or, if there is no stop line, beyond the light, unless you are so close to the line or the light that stopping would be dangerous. Flashing amber light: you may proceed only if it is safe to do so and, if appropriate, yield to other traffic. Flashing amber arrow: you may proceed in the direction of the arrow but only if it is safe to do so, and you must yield if other traffic is approaching. Failure to obey traffic lights could result in 2 penalty points and a fine of up to €120, or 5 penalty points and a fine on conviction. |

Forbidden drugsTHC (cannabis) Methylamphetamine MDMA (ecstasy) The current Road Traffic Act (RTA) does not mention any specific drugs and relies on the evidence of impairment of the driver by the police (Garda) and the Medical Bureau of Road Safety Certificate of analysis for the presence of a drug or drugs. The term used in RTA is “intoxicant” and defined as alcohol and drugs and any combination of drugs or of drugs and alcohol. The RTA does not distinguish between illicit drugs and licit drugs which can be prescribed medications or over the counter medications. The consideration of driving capacity or safety is the core element rather than the legal status of the drug. Currently the Bureau analyses for the presence of the following drugs or class of drugs:
