The city is investigating complaints that street-cleaning trucks have been driving the wrong way up one-way streets, endangering other drivers and creating traffic jams, reports Yediot Tel Aviv. Numerous residents in a number of streets have reportedly complained that the trucks simply ignore no-entry and one-way signs as they go about their work. According to the report, residents have sent the city photographs of trucks heading the wrong way up one-way streets. Some residents said that when they complained to the drivers that they were travelling the wrong way, the drivers responded that they were allowed to do so. The city has forwarded copies of the photographs to police, saying that as well as creating traffic blockages and endangering other drivers, such actions are illegal. A municipal spokesman was quick to point out that the errant trucks do not belong to the municipality, but to the company hired by the municipality to carry out street-cleaning work. The spokesman said no vehicle was authorized to break traffic laws, and the city was regarding the matter with the "utmost seriousness."
