How to report a traffic violation to the police in Singapore

If member of the public wishes to report to the police of a traffic offense or violation that they encountered in Singapore, they can do so by following the minimal requirements stated in the Singapore Traffic Police website. The furnished information is necessary to build a strong case against the traffic offender.

•  Full registration of the vehicle of which the driver/rider committed the traffic violation/offense (if possible, provide the make and colour of the vehicle).
• The accurate date, time, and location (precise location would be required, i.e. as how you would provide your location to a tow trunk operator) of the alleged offense.
•  The circumstances/accounts leading to the alleged offense. If it's a parking offense, I guess you don't have to provide this (but sometimes you have to provide evidence showing that the vehicle was not stalled due to engine failure, e.g. a before and after pics or video showing the offender driving off afterwards, thus suggesting that his vehicle was not defective but rather he/she parked indiscriminately).
• Confirmation of willingness to testify in court should the offender dispute the alleged offense. This is important should the offender dispute the offenses alleged against him/her. The drawback is that if it was a foreign traveler to Singapore, he/she will be unwilling/unable to testify later. However, if Singapore court allows written- or video-recorded testimony, then justice will not be hampered by technicality.
• Full particulars of the informant. I guess if you are willing to testify, then you have to provide full particulars of yourself. Definition of full particulars would be your full name, NRIC/passport/ID, address, contact number, and email (the last three items are required for investigation officer to contact you for help).
• Corroborative evidence. If you have video- or picture- recordings (explicitly showing the alleged offense taking place such as snapshots or a video account; a pic showing the aftermath of the accident is not useful) with correct date and time (remember to set your compact camera with this information; for phone camera, it's already preset ready), independent witness(es) to corroborate your account (if you have a pen and paper, write down the date, time and location, and brief account; then allow the witness to write his/her particulars for your reference; you can then ask the witness to take a pic of the note with his/her phone camera; this is important because the witness might forget important information such as exact date/time/location later). The particulars of the independent witness should at least have name, contact informations (e.g. phone number and email address). Send video evidence to SPF_Feedback_TP@spf.gov.sg (quote the police report reference number on the email).

 Once the minimal requirement is met, they can approach Neighbourhood Police Centre (NPC) to submit a police report (form NP299). Alternatively, you can submit an electronic feedback to Singapore electronic Police Centre. The required login information SingPass user ID and password (What about individuals without SingPass?).

For your information, the e-feedback is available to report on the following:

1. GOOD/COURTEOUS road behaviour :D
2. Feedback on pedestrians'/cyclists' behaviour on Singapore road (or non-designated area such as open mall), 
3. Parking violation (reporting to LTA; types of illegal parking can be referred to Onemotoring.com.sg), and 
4. Traffic violation (on the road)
