The RTMC has been silent about whether these changes will be implemented. Although the proposal was presented in February 2022 as part of the 365 Campaign, no formal steps to amend regulations have been taken.
Simon Zwane, the RTMC’s chief communication officer, stated the reductions align with international road safety efforts and have government support. However, critics argue that the emphasis on speed limits is misplaced.
Criticism of Speed Limit Reductions
Road safety expert Rob Handfield-Jones and others question the effectiveness of reducing speed limits:
- Speed is Not the Main Factor in Fatal Accidents:
- According to a 2003 study cited by Handfield-Jones, only 7.9% of fatal crashes involved speed, while 92.1% were caused by driver errors.
- Incorrect following distances and insufficient awareness are seen as far more significant factors.
- Historical Evidence Against Speed Reductions:
- In 1998, South Africa experienced its safest road conditions despite having higher speed limits.
- Lower speed limits for public transport vehicles (120km/h to 100km/h) reportedly had no positive impact on safety. Instead, bus occupant fatality rates rose nearly 30% in a single year.
- Potential Dangers of Low Speeds:
- Slower speeds might pose risks. Research by Leonard Evans in Traffic Safety suggests a crash at a delta-V (change in velocity) above 115km/h is uniformly fatal, regardless of legal speed limits.
The Case for Lower Speed Limits
The RTMC and UN argue that reducing speed limits can help:
- Minimize crash severity.
- Improve safety in areas with vulnerable road users, such as pedestrians and cyclists.
Proponents believe that while enforcement and other measures are essential, lower limits are part of a broader effort to improve road safety.
Implications of Speed Limit Changes
- For Motorists: Reduced speed limits could result in longer travel times and potential frustration.
- For Law Enforcement: Increased focus on speed monitoring might divert resources from addressing other causes of accidents.
- For Road Safety: The debate underscores the need for comprehensive solutions, including better driver education, improved vehicle safety, and road infrastructure upgrades.
Conclusion
While the RTMC aims to align with global road safety standards, critics argue that reducing speed limits is a simplistic solution that overlooks deeper issues like driver behavior and enforcement strategies. Without credible data to back its effectiveness, the proposal remains contentious.
